Customer Reviews | Backpack Airflow Ventilation and Spacer

"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."

"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 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."

"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 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."

"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!"

"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!"

"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."

"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."

"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."
