See Why Backpackers Love The Cool-Dry Frame. 

"I'm at the top of Mount Baldy. I have my Cool-Dry Frame to keep my back dry. You can see that it creates space so air can go through. Thank you for a very useful tool."

- Michael T, Mount Baldy, Southern California

Sweat less when backpacking

"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

"Loving the Cool-Dry Frame! It's perfect for every season. Now, I never ruck without my Cool-Dry Frame. Held up even better with the 45lb ruck plate."

- Max D, day training with a rucksack, Detroit, Michigan

Rucksack frame airflow system

"My conclusion is that the Vaucluse insert definitely keeps things drier and cooler. On these points, I rate the Vaucluse Cool-Dry Backpack Frame at 100%!” ~ read full review here.

- Joe Schaffer, Medium Gregory Palisade 80, 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.

"Holy cow am I a believer in your product! Worked fantastic in Georgia with my hiking pack on and like 40000% humidity this morning! Super comfortable! I'll get my wife to get some pictures of the sweat pattern the next time we go out!"

- Chris, day hiker with 20L pack, Georgia

"I have the back practically dry after a three-hour hike in the heat, therefore I recommend."

- Hubert T, day hiker with a 20L backpack from Vaucluse, France

"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, day hiker with High Sierra Cirque 30, 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

"I wanted to say it really worked well even in the cold conditions we had I was still sweating with just a base layer, but my back stayed dry on some heavy-duty hikes."

- Matt C, multi-day hiker with a 30L backpack from 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."

- Jared O, birdwatcher with North Face day pack from Oregon
