CUSTOMER REVIEWS

Read the every-growing number of 5-star reviews from customers. It's clear that Vaucluse Backpack Ventilation Gear is improving the outdoor experience for backpackers.

"This ventilation frame works. 23 mile hike in the White Mountains of NH, including the Bonds and Zealand. Just under 12 hours elapsed time. Temps upper 20’s to low 30’s.

I hike every week, all year, in all temps and conditions. A sweaty back can be a real problem in cold, winter weather. My back would always get sweaty, then freeze when I stopped to take my pack off to make a gear change, eat, etc. Having used this frame now for a few weeks, I have not had a sweaty back. Plain and simple… it works."

"I hiked Kepler, Milford, and Routeburn Tracks in NZ covering 85 miles at 30 min miles, hiking 4-6 hrs per day in cool weather from rainy in full rain gear to cool but humid conditions.

The ventilation frame performed superlatively. It was comfortable, at times completely unnoticeable, while keeping my back much cooler. If it didn't rain, the backpack was completely dry. My shirt was as significantly drier than without the frame. Essentially, the only sweat lines I had were where the hexagonal portions touched my back. Basically, I was as dry as I could possibly be considering I was sweating from effort, and not from my backpack sitting on my back."

- Sang, Hyperlite Southwest 3400, California


"I attached the Vaucluse Gear Ultralight Ventilation Backpack Frame on a Gossamer Mariposa 60L. Hiking Big Cypress North on Florida Scenic Trail. 23 miles day 1. 8 miles day 2. Almost no elevation (it's Florida!). 23 hours in 8 hours moving. I burned 3400 per Garmin. The weather was humid, 85, and sunny for the first day. The second day was rainy.

The airflow on day one was AMAZING! While I was still hot, I could feel the breeze on my back, and it was HEAVEN! An absolute dream to not have a hot, thick pack sitting on my back.

My friend hiking with me had heard of them and was quite taken by how great this was. My pack and shirt were both marginally wet. But mostly just from where my hips/butt touched the bottom of the pack. I wore a tank top all day and had no discomfort hiking all day. While I could feel the plastic, it was not irritating at all. I had zero hot spots or chafing from it."

- Amber, Gossamer Mariposa 60L, Florida, @liveliftrun


"My background is camping and hiking, Search and Rescue, Rope Rescue, EMR (wilderness first responder and medical gear), and hunting. I have three decades of experience with cheap, expensive, and too much and too little gear on my back.

First, the frame breathes! Not just seeps or wicks, but this BREATHES like a menthol rub across my back with the slightest breeze or movement, so this will now allow a backpack or at least a hydration pack on windless summer hikes in the Phoenix Valley. We hike even above 110 degrees. The heat and moisture ventilation means you can stay in long sleeves and regulate body temperature better while protecting yourself from the sun and the elements. It removes any compromise that would jeopardize health and safety.

Second, the frame gives structure to frameless packs. It adds enough structure to make a good "car bag" great for several miles. I'm eager to see what my heavy, sausage-shaped car bag can do on a hike over four miles and will report back after.

Third, the frame distributes weight! I feared it would cantilever the load and pull my center of gravity back. Sure, I can't deny physics, but so does an expensive pack's attempt at foam and mesh with only a fraction of the benefit this sturdy breeze tunnel creates. I was waiting for it, even expecting it, but I didn't experience a sense of the load being over-leveraged. The frame distributes more evenly side to side and up and down.

Overall, I'll be buying more frames for family and friends. I cannot wait to try it on cold camp hikes and on Phoenix Valley summer trips."

- Jeremy, Norfuma Tactical Rack Bag 36L, Cave Creek, AZ


"I own a total of 4 of these ventilation frames. Two original (Gen 1) and two Generation 2 (in photo). If you want excellent ventilation without buying a new pack, please check these guys out.

Wonderful company to buy from."

- Scott, Hyperlite Backpack, North Carolina


"I attached the ventilation frame to my North Face Recon (30L). My back was dry. I started with three layers: synthetic shirt, fleece jacket, and puffy. With all three layers on, I didn't notice the frame at all (very comfortable). With just two layers (shirt and fleece), I did notice the frame a little, and every once in a while, it felt a little pressure on the mid-right side of my back, but then it would go away. My pack was fairly light, probably around 10 lbs total. I imagine without the fleece I would feel the frame more with just a synthetic shirt on. I will try this when it warms up a bit."

Note: Vaucluse Gear has released a mesh sleeve that goes over the frame in response to customers' requests for additional comfort.

- Jake, North Face Recon (30L), California


"I hiked Tom’s Thumb in Scottsdale, Arizona. 4.5 miles. 1200 elevation gain. I wore a small hydration pack.

Airflow was nice, my shirt was wet afterwards but not my backpack so ultimately it made a difference. I could feel the breeze on my back. It was pretty comfortable, I only felt it a bit at the pointy bottom of my shoulder blade. I did get some questions from other hikers that were curious. They loved the idea of this!"

- Suria, Hydration Pack by Mubasel Gear, Arizona


"My backpack was dry and the breeze on my back was great.

I was still sweaty but I am always sweating when I hike. And it was comfortable."

- Eli, Hyperlite Mountain Gear Windrider 55L, Mohican State Park, Ohio


"Wore the Ventilation Frame on my Gossamer Gear Mariposa 60 for Appalachian Trail Section Hiking.

Loved it. Didn’t even know it was there and provided good ventilation. I had some friends that got some too. They were wearing theirs too low and didn’t like it. They moved it up on their pack and it worked great for them."

- Kyle, Gossamer Gear Mariposa 60L, Alabama


"I wore the ventilation frame on my 60L BASE Jumping stash bag. Hiking up a cliff to base jump. I’ve gotten a couple shorter hikes. It worked well for the upper back, but the backpack was too long and by my waist the backpack collected a lot of sweat.

A longer frame would be nice, and if you're interested in the BASE jumping market, a way to disassemble it that makes it flat."

- Tarik, 60 L BASE Jumping Stash Bag, Nevada


"I attached the frame on my SWD Movement 35L backpack. Backpacking, 20 mile round trip, cool/cold weather, 4,354 ft gain. Worked great, almost dry shirt and pack. Other packers had wet backs. Plenty comfortable, hardly noticed the frame.

I trimmed the length to fit an existing sleeve which may not benefit many customers, but I could imagine a reduction in thickness might be desirable."

- Nick, SWD Movement 35L, Central California


"I have only had 2 hikes with the frame. The first was about 7 miles, 2000 ft elevation change, 50 degree-ish temps in the Shenandoah National Park. The second was 10 miles, 2000 ft elevation change, 30-degree temps also in the SNP.

During my 50-degree hike, I was pleased that my back was dry throughout. Normally even at 50 degree, my back would have been soaked and then I would get cold when I took my pack off. I could feel the frame on my shoulder blades through a single layer t-shirt. I would not say it was uncomfortable, just an awareness.

On the colder hike, I had multiple layers and did not feel the frame at all. No sweating at all anywhere that day. I look forward to testing the frame on a warmer day with a single layer to see if there are any hot spots."

- Kathryn, ULA Ohm 2, small torso, Virginia


"I added the frame to my Hyperlite Mountain Gear Daybreak 17 on two hikes, 5-6 miles each, around 1,500 ft. elevation gain at 10,000 ft. Both clear weather in winter, around 30-40 degrees.

The Ventilation Frame performed quite well. Even in winter, I usually sweat quite a bit with this pack, given the pack is Dyneema construction with no built-in ventilation. With the frame, I sweat far less, and I kept my jacket on to stay warm (I usually compromise by either being somewhat cold and less sweaty or warm and having my back soaked). However, comfort was a slight concern towards the end of the hike. The distance between the pieces of the frame became noticeable as they started to dig in a bit towards the end of the hike. The frame moved around more with a lighter load (e.g., when I had my spikes/mid-layer on, so the bag wasn't as packed out, much like it is in the photo). This wasn't a huge issue; it just made me slightly less confident when maneuvering around trees, etc. Overall, I'd give it a 4/5."

- Nick, Hyperlite Mountain Gear Daybreak 17, Colorado


"I used the ventilation frame on an Osprey Daylight. Hiking between 5-9 miles on medium to rugged terrain in the northeast US. In the fall and winter, mild rain, snow, clear skies, and wind.

The airflow on my back with the Daylight is superb! My jacket/shirt stays dry, no sweaty back. My Daylight stayed dry, too (on the back). I only carry about 5-7 lbs in the day pack. The frame is very comfortable. I don't really notice it's there except that I can feel lots of airflow and breeze on my back.

As a ventilation system, it's great. However, what I need help with is that the top hooks that go around my backpack straps and snap into the frame come undone (note: We now provide reusable zip ties, which have solved this issue). I look forward to trying it out in the spring and summer!"

- Suu, Osprey Osprey Daylight, Massachusetts


"I have done several short (3 miles) winter hikes in western Massachusetts. Slightly hilly with some ice and snow.

I like the frame it’s comfortable and I feel like there was less perspiration on my back. I am curious about how much less I perspire in warmer temperatures."

- Jack, Kelty Redwing 65 L, Massachusetts


"We hiked 5 miles near Lexington, Kentucky over 2 hours in 60 degree weather.

Although the temp was not bad, I could tell a big difference in the amount of air flow. Our packs usually sit directly on our backs. We had pit sweating but none on our backs. They felt great."

- Lonnie, Osprey Raptor and Osprey Raven, Kentucky


"I added the ventilation frame to my Zomake 40L which I use for light hiking.

The airflow was great, I appreciated having a sturdy base so items were not poking into my back and that my hair did not get caught in it."

- Kristy, Zomake 40L, Pennsylvania


"I just got a Bearvault 425 (bear canister). The smallest one. I eat keto and intermittent fast, so i hope to be able to hike long distances with less food. I wasn’t sure if a Bearvault would work in my Cutaway. It fits, but was uncomfortable — until I attached the Vaucluse! This is a huge selling point for your frame and you should advertise it that way for PCT hikers and anybody needing a bear canister. I was worried I’d have to swap out my cutaway for my zpack’s arc haul. I love the cutaway and lack of hip belt. The only worry I’ve had for the entire PCT has been the bear canister sections—and now I’m golden.

Airflow is great but I wish the frame were 1-2 inches shorter for my 16 inch pack backside. The Nashville has an underneath pocket so it’s important the frame not get in the way. It works as is but would be better if shorter."

- Rick, Nashville Cutaway 30L Ultralight Backpack 16 inch, New York


"I hike 4-7 miles five times a week. PNW bush terrain in all kinds of weather.

Zero issues. Back stays dry now, barely feel the frame on back."

- Ross, Military Level III Assault Pack, Oregon


"I’ve gotten a couple shorter hikes. Northfield Mountain (MA) 4 miles, 699ft elevation, 2 hours in rainy conditions. Mount Monadnock (NH). 3 miles, 1,453 ft elevation in 3 hours. Cloudy, windy upper 20s.

The frame was quite comfortable for the duration of both hikes. I could definitely feel air flow on my upper back. My shirt and backpack were slightly damp but not drenched as usual!"

- Nicky, REI traverse 60L, Massachusetts


"I’ve tried it for about 12 hours of hiking now with about a 10 lb pack. I originally bought this to use with a Zpacks Nero to help with back sweat. Since then I’ve also tried it with a Gossamer Gear Fast Kumo with amazing results.

My first impression after 5 minutes on the Nero was that the frame is fairly narrow and it feels a bit strange on my back. After 4 hours I barely even noticed it. My conclusion with the Nero is that it works okay but it adds a couple ounces and I would probably be better off with a Zpacks Arc Haul since it already has great ventilation.

Then I tried it on a Gossamer Gear Fast Kumo. The Fast Kumo is already a narrow pack. After cutting off the hanger at the top of the frame it fit perfectly. It’s like it was made for it. This pack is designed for fastpacking already so it’s easy to get hot. Using it on a 12 mile hike I would still sweat a little but it’s way better than the original pad and GG’s own ventilation pad. It’s a great combo and I can’t wait to get out on the trail with it again."

- Daniel, Gossamer Gear Fast Kumo, Georgia - click to read original Facebook post


"I attached the ventilation frame to my Teti day backpack. It's my daily bag for work.

Everything remains dry, definitely helps when wearing a dress shirt for work."

- Gavin, Teti work backpack, Maryland


"I have have three back packs. My main one is a custom moose track pack body with a Gossamer Gear hip belt and six moon designs running vest style flight harness. I took the UL ventilation frame on an 11 miles hiking ,running and jogging - some low elevation various pace. Cold weather.

Air flow was great - almost to cool. Backpack was dry. Back was only damp where frame makes contact. Comfort was okay. Experienced some pinching between frame and shoulder blades when I would run fast with arms moving quickly and shoulder blades sticking out some."

- Anthony, Custom Backpack w/ components from Moose Track, Gossamer Gear, and Six Moon Designs, Iowa


"Overnight backpacking trip 8 miles round trip, SoCal, 55/28 temps with my my Granite Gear Virga 3.

Definitely felt the cool air under the pack in the mornings, comfortable for the entirety of the trip."

- Steve, Granite Gear Virga 3, Southern California

"Installed the UL Ventilation Frame on Zpacks Arc Blast & KUIU Stalker 500 Pro.

Only attached to the said packs to see it I thought it would work and walked around the house. Liked it enough I ordered two more for gifts."

- Travis, Zpacks Arc Blast & KUIU Stalker 500 Pro, Indiana


"I use a Zpacks Nero 38L pack. Overall I really enjoy the ventilation system during warmer weather."

- Raymon, Zpacks Nero 38L pack, Alabama


"Airflow was significant! Back still sweating but cool air keeping me cooler. Seems very comfortable in winter. Summers coming!

Shirt was lightly damp (usually WET) but camel was dry except shoulder/waist straps."

- Wade, Camelbak KUDU 12 w/back protector, Louisiana


"I attached the ventilation frame on my 5.11 LV Covert Carry 45L. The airflow was excellent. On cooler Florida days like today, I usually end up with a sweaty back, and everything else is dry. No issues today, and I can feel a breeze when I walk. I really like this.

Comfort is also pretty good, but I feel a few things missed the mark. First, the loops that connect to the top of the backpack straps come undone almost every time I take the pack off. I had to wrap them in electrical tape to keep this from happening. If the connections between the frame halves and the loops at the top were more secure, it would be an absolute home run. Overall, I am very impressed; maybe the next version can address these issues."

Note: Vaucluse Gear now provides additional reusable zip ties to assist in securing all the connections of the top loops. This resolves the user's issues.

- Sean, 5.11 LV Covert Carry 45L, Florida


"Snowy hike up the Tecumseh Trail with an old friend for number 10 of the NH 48 4,000 Footers.

I'm thankful for the extra ventilation!"

- Joe M, Hill People Gear TARAHUMARA PACK, New Hampshire @joemitch25


"This was so amazing to have on my pack traveling around Vietnam and Philippines. So many people asked me about this and after letting them try it on my pack, they had to get one too. Best product I have ever tried."

- Rodney, Travel Daypack, Southern California @rburnes


"Hiked generally intermediate distances of 4-8 miles each time.

The Ultralight Ventilation Frame worked as advertised. It kept my shirt much dryer than normal. Light weight and comfortable."

- David G, 22L Backpack, Southern California


"I hiked Black Mountain with Brice (President of Vaucluse Gear), 2.5 miles, 1,200 ft gain, 2 hours, clouds/sprinkles.

I felt the airflow was greatly increased. My backpack was dry, my shirt was almost completely dry. The front of my shirt and back were the same moisture level. I found the Ventilation Frame to be very comfortable and almost feels like a nice massage on the back."

- Jared, REI Trail 25, Cave Creek, Arizona


"I do a lot of hiking which usually includes wearing a backpack and that almost always means having a sweaty wet back. Well not anymore!

This morning I went on a hike and tested a new piece of gear from Vaucluse Backpack Ventilation Gear, and my back stayed nice and dry!

This lightweight frame creates a comfortable airflow space between your back and your pack and can be used on any pack you already own. I know it will be staying on mine."

- Andy, Osprey Daylite, Phoenix, Arizona


"Installation of the Vaucluse ventilation frame was simple: took no more than two minutes. The frame weighs just a couple of ounces, so I knew the weight wouldn’t be an issue.

My impressions of the frame are totally positive. As advertised, it eliminated the sweat that would build up between my back and the pack. Truly amazed that the ventilation gear performed in this area so well.

Backpack manufacturers have gotten very sophisticated with the design and fit of their packs. I was concerned that using the Vaucluse Backpack Ventilation Gear would negatively affect the pack’s performance. Turns out, this was not an issue at all. If anything, it improved the performance of the pack.

Weight distribution was not a problem. Even though I had space between my body and the pack, the pack remained very secure, and did not drift as I walked, climbed or descended. In summary, I highly recommend the Vaucluse Backpack Ventilation Gear!"

- John B, REI Co-op Traverse 32L with a 3-liter hydration bladder, Cave Creek, Arizona


"Went on a 5 mile hike with the Vaucluse Backpack Ventilation Frame on my WANDRD 41L PRVKE. My back and pack were far more dry than would have been without the frame."

- Shane, WANDRD 41L PRVKE, Mesa, Arizona


"The frame will fit just about any backpack you can think of. One of the best things about it is the price and discount.

The frame was comfortable. I did not notice it on my back after a short period of time. It did feel a little strange when I first put it on. Even though it is very strong vertically, it flexes so well that it conforms to whatever back shape you've got. With the backpack pressing on it, it just provides a little bit of a shock absorber.

I was concerned about pushing the backpack off of my back; however it doesn't make a huge difference. If you think about some of the packs out there, there is a wider gap between the ventilation screens and the pack.

If you are tired of having a nasty sweaty back and don't have a pack with good ventilation, or you don't want one with the mesh built in, this Ultralight Backpack Ventilation Frame might be just for you."

- Doug, 28L Waymark Mile Daypack, California, YouTube Channel Backcountry Pilgrim


"My back was much less soaking wet than it usually gets on hikes. My wool base-layer was damp so it felt warmer than usual and much more comfortable despite the top hinges of the ventilator not staying clasped together.

I was able to tuck the bottom into my backpack so that helped it stay in place and I think if my gear is organized differently, it might perform even better."

- Kris, Gossamer Gear Kumo 36, New Hampshire


"Best backpack support. Dry and comfortable all the times where walking."

- Tommy R., 30L Supreme Backpack, Maryland


"Miraculous! I purchased the Generation 1 Ultralight Frame one a year ago and loved it. The original one blew apart from overuse. Now I am due for another one (Generation 2 Frame).

I use the frame hiking in New England in all of the seasons including winter. I hike about 20 -40 miles per week. Elevation is variable. I completed The 2, 3, 4th tallest peaks in New Hampshire in one day last summer with the Vaucluse Gear Ventilation Frame. It was fantastic in June. No sweat."

- Jonathan C., 54L ULA equipment model CDT, Berlin, CT


"Absolutely loved the light weight design, and it seamlessly fit onto my pack. At times, I forgot it was even attached. It significantly reduced the amount of sweat on my back and the cool air flowing through was amazingly soothing.

The ventilation gear is a welcomed edition to my hikes."

- Paul A., North Face Borealis Outdoor Backpack 28L, Phoenix, AZ @hiking_padawan


"It worked fantastic!

Wasn’t sweating and barely even noticed it was in my pack, but certainly felt the difference."

- Jay W., Rockagator and Eberlestock backpacks, New York


"Currently working on the NH 52 With A View, have completed 6 of them with the Vaucluse frame, between 1,000 a 1,800 eleven gain, 3-5 hours each, 95% humidity, rain and sun.

I sweat a lot, but the frame has been great! Hiked today, started at 38°F, 1,400’ gain, some rain, the frame allows for great airflow that keeps me from overheating."

- Patrick S., Deuter Speed Lite 30L & REI Flash 22 (22L) Ultralight, New Hampshire


"The frame's plastic (High-Density Polyethylene (HDPE) is FDA-approved, recyclable, non-toxic, and used to make food containers such as milk jugs) conformed to my back shape, which I consider a plus. It feels flimsy, though held up well. It definitely helped with keeping my back dry.

The male-to-female connectors on the loops were easy to knock loose from putting the pack on/off, and from branches, etc." (Velcro is now provided with the frame to better secure loops).

- Ben V., 30L Daypack, ModGear hydration pack, 16" x 9" x 3" main compartment, West Brook, CT


"Yesterday's hike was pretty wonderful. Even more so because I finally tested out the ultralight ventilation pack frame I bought from Vaucluse Gear.

It's not a secret (any of my hiking partners can agree): I sweat. A LOT. Embarrassingly, to the point I soak literally everything I wear on the ascent often joking to help make my pride feel better about how I look like a wet poodle. With Floki's added weight(+15lbs or more) on top of all my other gear I have been desperate for some sort of solution.

I heard about this frame on a @slasrpodcast, and it simply attaches to my pack easily and provides a space between my pack and back to help create space for airflow, reducing the heat my back puts out and minimizing the sweat, at least in that area, helping with comfort and cooling. Now to only figure out how to help my head because that's where most of it comes from. Damn Scottish genes. It worked really well and definitely minimized heat, and my pack was dry when I returned to my car. I'll take that any day!"

- Melissa, 30L Daypack, The Cherry Mountain Trail a.k.a. 1.8 of Vertical Hell, New Hampshire, @adventureswithflokicat


"I had doubts about the comfort of an add-on backpack ventilation frame, but after a few minutes, I barely noticed it was there. It's a terrific product!

I sweat a lot during exertion, especially with my UL frameless packs that offer no ventilation but hug the body well. The Vaucluse Ultralight Ventilation Frame performed exceptionally well. It is so light and surprisingly comfortable. For my first run, I paired it with my Mountainsmith Zerk 30 Pack. I loaded the pack up with about 14 pounds of weight. I feel that I could load up to whatever the pack is rated for without issue. One of the best incentives that this product offers for me is the "no cold back attack." When you take a break after hitting a saddle or summit, I like setting down my pack for a break. When you're ready to head back out, you throw your pack on, and the cold sweat from your shirt and pack hit ya is soooooo annoying to me. The Vaucluse frame fixes that for me with no issue. I also love that I can easily hot-swap it onto my other packs."

- John W, Mountainsmith Zerk 30 Pack, Phoenix, AZ @jvasholz83


"It greatly improves airflow. The bag is usually dry but shirt not so much - still sweating of course.

Performs pretty well."

- William C, Camelbak Lobo Hydration bag, Laguna Woods, CA


"This is way better. Love it, brother.

I did 6 miles over 2 hours. I definitely didn’t experience back sweat with this pack, with the exception of the lumbar pad, which was not covered with the Vaucluse frame.

Overall, it works as advertised! Awesome product."

- Carlos B, Mystery Ranch Backpack, Cheyenne, WY @catholicammo


"My backpack's airflow improved, and the frame made a notable difference. I will still sweat, especially if wearing a sweater, but it feels more like sweating without a backpack. You don't get your entire backside drenched in sweat as you usually would."

- Jonas R, 5.11 Rush24 37L, Viby, Denmark


"The frame has definitely helped with my body temperature regulation. In the winter, my back stays dry between my coat and pack. It has helped with over heating in the summer."

- Amy M, Women's 30L Osprey Tempest, White Mountains, NH


"Noticeably drier. Only patches of sweat where the frame contacts my back. Comfort was excellent.

Summer hiking from Southern Utah to Oregon. Daily rucking sessions. Temperature from 41 to 100 degrees. More than 1,000 miles."

- Dustin H, DSPTCH Daypack, Hill People Gear Umlindi, GoRuck GR1 - Providence, UT


"I attached it to a carbon fiber seat on a recumbent tricycle I commute 42 miles roundtrip in southern Arizona.

Temperatures can be well over 100F. The air gaps helps keep my back from overheating. I used a USB fan to blow air across the seat through the gap."

- Sandiway F, Carbon Fiber Velomobile - Oro Valley, AZ


"Airflow was remarkable."

- Alejandro R, Osprey Manta 24, Osprey Talon 44, Omm Classic 25, Ortlieb Attrack 45, Kurgo G-Train Dog Carrier - Spain


"I am a park patroller in the Denver metro area, so I’m excited to use the frame to provide more ventilation. I could tell a noticeable difference in ventilation, especially on the day pack since it has no attempt at ventilation whatsoever, but even with the Granite Gear, which does have an attempt at providing some ventilation. The Vaucluse did a much better job.

I was wondering if the bottom of the frame would irritate my back around the belt, but it did not do so. The pack still felt close to my body, and an added bonus is that if I do happen to pack my frameless pack not totally flat, the frame evens out any bumps.

It’s easy to switch the frame from one backpack to another."

- Rolf D, Volpi Outdoor Gear “Falco” 25L pack (18”H, 12”W, 5”D) and a Granite Gear 60L Crown 60 - Denver, CO @rolfdenvers


"I attached the frame on my Mystery Ranch Coulee 25L, Zerogrande 30L, and Tumi Tech Hiking. I took the frame on a 2 hour hike over hilly terrain. The frame performed very well and added support to the Zerogrande backpack which does not have a frame. My back was dry, felt cool."

- Benjamin W, Mystery Ranch Coulee 25L, Zerogrande 30L, and Tumi Tech - California


"The frame works extremely well. You should market it for oxygen concentrators! It is great to keep the heat off my husband's back!!"

- Sharon W, Portable Oxygen Concentrator Backpack - North Carolina (attending Penn State vs Ohio State football game)


"The ventilation frame is very comfortable. Some wetness though I would say about an 80% reduction. I put the frame on my Marmot Kompressor Plus. Hike was 8 miles, sea level, 3 hours, 75 degrees."

- David M, Marmot Kompressor Plus 20L - New Jersey


"The ventilation frame worked incredibly well in warm temperatures. I had noticeably less sweat on my back and it felt much cooler than days that I didn't wear the frame. It actually helped more with the Targus bag because that bag doesn't have a frame built in like the Osprey. Both backpacks benefited from the increased airflow the frame provided, but the Targus backpack was also benefited by the structure of the frame."

- Adam C, Osprey Talon 22L and Targus City Backpack 20L - Seattle, Washington


"As for using it as a baby front carrier spacer (which, to my knowledge, there is nothing on the market), it was a little tricky to hold it in place with a light blanket and mount him, but it did work pretty well. I went on a walk in 80+ degree weather, which generally I would be soaked with sweat, even with putting a towel between us.

One thing I’ve loved about Osprey backpacks is what I thought was the ventilation. But I didn’t realize what I was missing. Adding the additional ventilation to the Osprey Poco Child Carrier made it that much more enjoyable and less sweaty. Hooks in nicely, and I could definitely feel the breeze coming through."

- Matthew R., Lilly Front Baby Carrier & Osprey Poco Child Carrier Backpack - Kent, Washington Instagram @MatthewJRichey


"Spent three days in the Jefferson wilderness in Oregon. That’s Mount Jefferson behind me. First longer trip with the ventilation device in place. Loved it. Super comfortable. A total game changer for that Hyperlight pack that normally sits right against your back with nonbreathing fabric."

- Jeff G, Eugene, Oregon, Hyperlite Backpack


"I can feel a breeze already coming through the back of the backpack and cooling me off where I'm already getting a little sweaty I can definitely feel that there's a cooling effect so far I was not expecting that. So far I'm kind of surprised."

- Zac Magers, Los Angeles, California, Kakwa 55L, YouTube channel @zacmagers


"Worth its weight in gold. (It weights next to nothing). My back stayed dryer and cool for 9 hot humid miles. The Vaucluse Ultralight Backpack was an absolute welcome! I won’t hike again without it!"

- Sara W, New York, 24L Osprey Tempest, @sara_anne_williams


"The Vaucluse Backpack Ventilation Frame is definitely a game-changer. 🙌🏼 It’s 100% staying as part of the setup for all my photography strolls from now on. I hope more people get to hear about it to help the product develop even further! It has kept me dry and cool on my day-long photography stroll today. I 100% would recommend."

- Rafael B, Chicago, IL, 15L Everyday Backpack Zip by Peak Design, @rafa_xnta


"A nice upgrade for any backpack!

My pack was dry, my shirt was soaked (100% humidity and 93 Fahrenheit in Texas!) but it was nice and cool.

I barely felt the frame."

"It feels good. Did it work? Yes. I felt the breeze on my back. It felt nice. I am loving my backpack ventilation. I'll be loading more 'Real Guy Reviews' on my YouTube channel, so check it out."

- Paul W, Ohio, Bullet Ruck 15L and Goruck 4.0 Rucker 25L, YouTube video review


"I'm loving it. Walked up to the top of Diamond Head with the Vaucluse Ventilation Frame on my 15L Bullet. Works very well keeping your back cool. Would be great for a motorcycle or cycling.

I also took it for a 6 mile uphill walk with about 15lbs in it. It definitely works and keeps from soaking your pack.

Not very noticeable wearing it. I only had about 15ish pounds load up but it seems to work very well."

"Finally able to get out and put the Ultralight Backpack Ventilation Frame to work, and got it dialed in. Outstanding design! Huge difference, keeping a space between the backpack and back. Negligible weight, and much more comfortable than I expected it to be! I highly recommend it if your wearing a backpack out there! 🤙🏻"

- Patrick S, New Hampshire, 28L Daypack Instagram @patricksmart603


"The frame performed wonderfully. I am a heavy sweater, but the main thing I notice when hiking with a pack is the warmth generated on my back from the contact of my hiking pack. Although I was sweaty, I was noticeably less sweaty because there was room for airflow between my back and the backpack."

- Jacob, Mount Washington, New Hampshire, Deuter Speed Lite 30 Instagram @jakeski603


"Barely any back sweat. Took my sis-in-law on her first hike in the whites today and she didn’t hate it."

- Michael L, White Mountains, Osprey 36L Instagram @miadevaia


"19-mile hike for my 44th high peak climb Mount Allen in the Adirondack High Peaks. The frame fit perfectly on my 3FUL 55-liter backpack. I was carrying about 20-30 lbs with overnight gear. I noticed the frame massage on my back the first 4 miles and was worried it would act like a cheese grater. The vent worked on the long walk out 9 miles and the slab climbing up Allen.

The frame didn't cause any abrasion or bruising on my back. I was overall impressed with the quality and durability, and comfort. I could see my friend's back was a sweaty mess. My back was dry, as was my backpack. The temp was only 59 degrees Fahrenheit. I am most excited to try this on my winter climbs, where back sweat can be dangerous at freezing temps."

- Phillip, 3FUL 55-liter backpack, Central New York State


"Normally with this backpack, my back is soaked regardless of conditions as long as the ride is more than 10-15 minutes. It's basically just due to the nature of the dog being strapped into the bag With the way the dog sits inside, it causes the bag to stick directly to you back.

Using the frame, it pretty much makes it so your back is dry the whole time with this bag since there is no contact. It's much much comfortable to bring my dog on rides with me with the frame."

"Frame did a fantastic job of keeping a steady room for air between my back and my pack. Great for sweaty hikers…. like me."

- Jake S, Deuter Speed Lite 30L, Mount Washington - his first 4,000 footer @jakeskis603


"Frame installed on Heritage GR1 26L and a 40L top loader. Although it wasn’t a super warm day in NYC, there was no sweat build-up on my back nor visible on the bag. There were about 20 lbs of Flushing Groceries on my back, and I felt every breeze. The venting from my first use case was a shock. Amazing product! Although I did feel a bit of tension on my back after about an hour of carry, it went away after a while. Who knows, maybe this venting system can dub as a posture device as well."

- Sunny K, 26L and 40L backpacks, New York, New York


"My back has been consistently drier on hikes with the Vaucluse Backpack Ventilation Frame. The airflow is great, and my shirt isn't wet when reaching the peak. Overall, the frame is pretty comfortable, even when just wearing a sports bra.

I was hiking a 12-mile loop in Moultonborough, NH, near Mount Shaw and Mount Roberts. The total elevation gain was 2,200 ft. The temperature was sunny and in the low 70s. I was wearing a Salomon 20-liter Trailblazer backpack."

- CeLynn S, 20L Salomon Trailblazer, New Hampshire


"The frame works really well at keeping my back cooler and drier - especially in warmer weather."

- Jon S, Ohio, 25L Perry Ellis Laptop Backpack

"Little to no sweat on my shirt in the cooler temps. As it gets warmer I'm noticing typical sweat near the lumbar area and only minor sweat where the frame contacts my back.

It completely changed how the pack carries (10 essentials plus lunch and snacks and water) for the better.

It pairs perfectly with the day pack."

Backpack Airflow Frame

"The instant I put my bag back on with the ventilation frame on it and turned a breeze blew right between my back and backpack and, I was floored.

I had no idea it would be that big of an impact. My back stayed dry all day long, and I’m glad it did because when I gained altitude it got colder. Had I been sweaty, I would have had to add a layer again. As a bonus, at the end of the hike, I had no need to change my shirt before hitting up a brewery because it was dry and not sweaty. So thank you very much."

- James L, Massachusetts, Osprey Manta 24L, Instagram @james_phoenix86

Backpack Airflow Frame

"Used the Vaucluse Backpack Ventilation Frame/Spacer on a hike in the Catskills New York, Windham Mountain.

It totally exceeded my expectations. My back and shirt stayed dry. My shirt even stayed in place (did not bunch up mid-back like usual). I could actually feel a cool airflow on my back while hiking. It was very comfortable. I had wondered if the frame would dig in my back, but I did not even feel it was there."

- Mike D, Catskills New York, 19L Gossmar daypack, Instagram @mden

"Took my Vaucluse Ultralight Backpack Frame on a photoshoot in the sunny SoCal Beaches and loved how it kept my back dry the entire time! I never knew what a game changer it is to feel the cool air throughout the entire hike.

I was able to carry about 20lbs of gear in my camera backpack and not one moment did I feel overheated or uncomfortable.

This product is ahead of its time, and I cannot appreciate the thought and care that went into producing it to make it happen! Thanks, Vaucluse you’ve made my photography trips that much more enjoyable!"

"You seem to be the only company making any product that is ANYTHING like yours, and it's useful - arguably needed- and I love it.

I'm as dry as I ever am after a long walk.

I honestly think the Hyperlite 2400 Southwest backpack is more comfortable with the Vaucluse frame. I can walk 4 hours and nothing bothers me about the frame, the pack, etc."

"I'll tell you what I do feel: I feel air moving against my back. That's awesome. Because even though it's a cool morning, I'm warm enough that, if I didn't have this frame, I would definitely be sweating by now."

Iceland backpacking adventure

"Game changer! The Vaucluse Ultralight Backpack Frame worked so well on my pack. Barely did sweat at all. I hiked Mount Whiteface and Mount Passaconaway loop in New Hampshire. The total length of the hike was 12 miles, and the elevation gain was just over 4,000 feet."

Backpack Frame Increase Airflow

"Easily rates 10 out of 5 stars! The Black Lava Airflow Frame I bought is comfortable, flexible, strong, easy to clean, colorfast, and safe on all the fabrics I tested. It allows perspiration to escape, keeping my back drier and warmer in cold weather, and enables evaporative cooling in warm weather, effectively lowering my core body temperature. It also keeps prodding backpack items safely away from my back."

- Chuck T, Tennessee, Hiker/Rucker with 26L Ruck Pack and 38L Osprey Backpack

Increase Airflow Backpack Frame

"The Vaucluse Air Spacer is a noticeable different almost instantly. When climbing in the mountains in the winter especially it’s crucial to sweat as little as possible and the backpack is always the main culprit. This allows air flow that keeps it at a minimum and is minimally noticeable on your back. A fantastic product addressing a major need in the outdoors world!"

- James A, Adirondack Mountains, Lake Placid, NY, Osprey Kestrel 48L. @JamesAppleton46

Backpacking Increase Airflow

"I'm loving the frame. The biggest advantage the Cool-Dry Frame offers is helping you stay warmer once you get to your hunting location. Most of the time, when hiking to your hunting spot with a backpack, your back will overheat regardless of how cold it is.

In cold temperatures, nothing is worse than sweating in your clothes and sitting in a still position for a long period of time.

So by significantly reducing or eliminating upper body perspiration, you'll be much warmer once you get settled into your hunting spot."

"How much of a difference can the Cool-Dry Frame make? I'm here to tell you today that the answer is A HUGE difference by allowing air to flow freely between the pack and your body to evaporate sweat quickly!

The super lightweight frame attached easily to my 36 Liter Osprey pack. It was very comfortable, so much so I forgot it was even there. Today's summit temps with the wind chill were in the single digits/teens. Normally, when I stop moving, I would break out my down puffy to warm up because of how cold I would be from the freezing air hitting my sweat-soaked back. Today, that wasn't the case. I can't wait to try this Cool/Dry Frame in the summer! I highly recommend you check it out!"

- Michael L, Rhode Island, Osprey 36L Instagram @miadevaia

Backpacking Airflow System Sweat Hiking

"This product is life-changing. My back never got cold due to so much less sweat. I actually convinced two others to buy them, and they also had them on with excellent results.

When I set out, the temp was 18F, and it didn't warm up much during the day. Very windy on the summit above the tree line. The frame's comfort was very high. I am a heavy sweater, and although I still sweat beneath the pack, it kept the sweat to a minimum.

I occasionally felt cold air on my back which was a great feeling. My shirt was still damp beneath my jacket, but nowhere near the extent it usually is. Stats: 15.3 miles, 16 hours, 4,900 feet of elevation, and 6,970 calories."

Vaucluse Gear Sweat Airflow Backpack Review

"Loved it! The Vaucluse Ultralight Backpack Cool-Dry Frame provided excellent breathability around my back. It also prevented sweat from building up and causing potentially hypothermic conditions in the winter. It is especially important to regulate body temperature during the winter when you’re layered up. This piece of gear was very helpful in that mission.

We stayed dry and happy the whole day. The frame was comfortable and lightweight. I hardly noticed I was wearing it. The design is simple, easy to take on and off, flexible enough to move with you, yet durable enough to carefully hold the pack away from your body."

"It carried better than my Osprey Levity. The frame was very comfortable and kept my back cool even with multiple layers for the cold weather. It was absolutely wonderful at keeping my back dry. I will not hike without it from here out!"

Backpacking Airflow System Sweat Hiking

"I attached the Vaucluse Ultralight Backpack Frame to my Deuter 30-liter, and it made a difference. I hike all the time in the New Hampshire White Mountains. I tried the frame out on a snowy hike up the Flume Slide to Mount Flume: about 9 miles total on a 20-degree day with 1,800 feet of elevation in .8 miles. My back was noticeably dryer, as was my butt, which is usually soaked. So far, my hiking buddies have marveled at the results."

- Tom P, New Hampshire, 30L Deuter


"The Vaucluse Ultralight Backpack Frame performed better than expected. I was particularly impressed with the comfort. I started off with a jacket and started to sweat a little so I removed it. With one base layer, my back dried out and stayed dry the rest of the way. Overall, I am very happy with this performance."

- Lance M, White Mountains, New Hampshire, Deuter 36-liter

Sweat less when backpacking

"I used the frame with my go-to 75L pack. My concern was losing stability with the bigger pack. That was not an issue at all. The frame helped take some pressure off my shoulders. My back was not soaked like usual. The next day we switched, and my wife stayed dry and happy. Both packs felt more comfortable with the frame. It exceeded both of our expectations. I really appreciate you coming up with a solution to a problem I thought I just had to live with."

Sweat less when backpacking

"I hiked from about 10:30 am to 3:00 pm. The temperature was in the high 80s at the beginning and low 90s at the end. I did sweat less and was cooler than I normally am. The frame was comfortable. I'm also a college student with a 20-minute walk to and from class, and I use it all the time. It helps SO MUCH!"

Airflow Backpack Evaporate Sweat

"All my hikes (travels with a pack) are +/- 30 miles in the Chihuahuan desert along the Mexican border in the summer. I'm on the move all day, during the day. HOT (120+), dry, max UV, min humidity. Ran a calorie deficiency as usual. Water is by far the priority. I feel a breeze between my back and the pack. My back (and below) is cooler and much less soaked. Overall, I like it and will continue to use it."

- Rod D, Big Bend National Park, Texas


"I always sweat like a mother and then freeze as soon as I stop, so it was nice not to have my backpack soaked when I took it off to take a break and put back on. It was lightweight and fit well. I am always cold but sweat quickly and a lot when hiking which is a weird combination and hard to regulate at times."

- Joe Schaffer, Medium Gregory Palisade 80 (77L), California


"I've never felt that type of cooling out here in these temperatures. Now I'm getting much more consistent airflow and evaporative cooling around my entire core, and that is really helping me stay out and move harder and longer. It just keeps your core down that much easier.” ~ read full review here.

"It works. I have not experienced sweat on my back. The only area where I get sweaty is at the very bottom where the bag touches my body near the waist area and the straps touch my back. This is fine as it still significantly reduces the amount of sweat/water-loss by at least 80%."

- Aaron S, day hiker with a 28L backpack from Arizona


"I normally drip sweat like a faucet with my back being completely soaked like I was sprayed with a hose. I cannot believe how dry this kept me. My shirt was just as dry on the back as it was on the front. That has never happened when I wear a pack. Never! The gear was comfortable and I didn’t even really notice it."

- Jeff L, day hiker with SKYSPER Hiking Backpack 40L, North Carolina

"My back had a little sweat, but the same amount as if I didn’t wear a backpack."

- Abby R, High Sierra Cirque 30L, Indiana


“Yes, with the warm temps my back didn’t sweat at all…nice! So far I like what I see. It’s well constructed, lightweight, flexible, and doesn’t feel odd when wearing it (I thought the honeycomb and the spacers might be annoying)." ~ read full review here.

Airflow Backpack Evaporate Sweat

"Overall I had no issues with the frame's fit on my daypack (with 2 full bottles of water). I hardly remembered it was attached and didn’t bother me while hiking at all. I hiked about 6 miles. Starting temp was 65 degrees. The ending temp was 82. My shirt was a bit wet, and my pack stayed dry. I sweat a lot, but likely not as much if I hadn’t worn it."

- Rob G, day hiker with a 20L backpack from Texas


"Really comfortable. I hiked 6 miles (3 up and 3 down) in 80-degree weather. I put the frame on my day pack with 2 liters of water and some clothes. The frame was really comfortable, and my shirt was damp but not nearly as bad as it would have been if not using the frame."

- Jerry S, day hiker with a 22L backpack from California


"It worked really well, even in the cold conditions. I was sweating with just a base layer, but my back stayed dry on the heavy-duty hikes."

- Matt C, day hiker and photographer with 30L backpack, Pennsylvania


"First time I have hiked with my Search & Rescue pack and not come back with a totally soaked back. I am sold on the product and will continue to use it. Comfortable. Lightweight."

- Rod S, Search & Rescue Team, 40L backpack from Virginia


"I’ve taken it out 3 times for my daily walk to see how it’d behave. I tested on Sunday without it and had a sweaty back. In the 3 walks since, I didn’t have any sweat. So we’re on the right track. All the walks were in a t-shirt and light fleece jacket."

- Tyler F, day hiker with 35L backpack from Washington


"I did not sweat as much as normal with the extra space between my shirt and the Cool-Dry Frame. Felt good and had no gear issues."

- Walter S, day hiker with 22L Osprey backpack from North Carolina


"None. Before, my North Face day pack with mesh back always left me sweaty."

Ultralight Backpack Ventilation Frame

This Generation 2 Frame is the upgraded version of our previous ventilation frame. The frame is 50% light (weights only 4 ounces - equivalent to a pair of socks), much stronger, and more flexible on your back. The design also has zero impact on your spine. The frame enables continuous ventilation by making space between your back and your pack, allowing natural airflow to draw away excess body heat and moisture as you move.
