The Vaucluse Ultralight Ventilation Backpack Frame is an attachable backpack airflow frame that fits directly on your favorite backpack. Call it the no-sweat backpack frame. This backpack spacer attaches in seconds to your favorite backpack (framed or frameless) to upgrade airflow, reduce back heat, and increase comfort.
The airflow gap between you and your backpack is a uniform 0.75" (19 mm).
Sweat less on your next backpacking experience and enjoy the adventure more.
A Backpack Spacer that Maximizes Ventilation and Airflow
The Vaucluse Ultralight Ventilation Backpack Frame is an ultralight backpack accessory (weights 3.5 ounces - equivalent to one pair of socks) that naturally ventilates back heat. The frame attaches in seconds to your backpack and creates a uniform gap on your back for air to flow around you as you move. As a result, you stay cool and dry while wearing a pack.
The frame is adjustable to fit both men's and women's backpacks of sizes 15L to 55L.
As tempting as it may be to loosen your pack’s shoulder straps for more airflow, wearing a backpack improperly is unsafe. Its weight pulls on your body, causing neck, back, and shoulder injuries over time.
The Vaucluse Ultralight Ventilation Backpack Frame suspends your gear three-quarters of an inch (0.75") off your back. This gives Mother Nature enough room to carry away excess body heat and sweat.
Simply attach one to your favorite backpack in seconds without worrying about sizing or adjustments, and avoid injuries caused by improper fit.
The frame attaches to framed and frameless packs to provide superior airflow.
Vaucluse Backpack Ventilation Frames are made from the same material as milk jug containers. High-Density Polyethylene (HDPE) is FDA-approved and used to make food containers such as milk jugs. Non-toxic, food-grade, and recyclable. Safe for applications that directly impact humans.

The hexagonal design maximizes your back’s exposure to air with minimal material. The design scales down the frame's weight to just 3.3 ounces. Vaucluse Ultralight Ventilation Backpack Frames weigh 3 times less than alternative mesh frames.

Ultralight Ventilated Backpack Frame Features
Ventilation Frame is Unisex - The frame quickly attaches to any backpack with the universal backpack strap loops. The frame is designed to fit onto every backpack - regardless of shape or size.
Stay Cool and Dry - When your pack is strapped on tight, your back can't breathe. The Ultralight Ventilation Backpack Frame allows air to flow around you as you move, naturally ventilating your body and helping to minimize unwanted heat, moisture, and scent.
Dead Air Space - Dead air space is the unventilated air space between your body and your equipment and clothing. Dead air space keeps you warm. Your backpack compresses your clothing and crushes the dead air space. You sweat because there is nowhere for the hot air to go. The Ultralight Ventilation Backpack Frame from Vaucluse protects the dead air space on your back to keep you warm while not sweating.
Increase Backpack Ventilation - Ventilated backpacks help keep your back and shirt drier by encouraging airflow behind your back and faster evaporation of perspiration. Let's be honest: most backpacks don't have any ventilation. The Ultralight Ventilation Backpack Frame is the only product that provides consistent back ventilation.
Regulate Your Core Temperature - A lot of heat can build up between your back and backpack. Large backpacks are especially notorious for increasing your core temperature. By keeping the pack off your back, the frame helps you regulate your core temperature.
Fits Backpack Sizes 15L to 65L: The frame is designed to fit across your shoulders and down to your waist for backpack sizes between 15L and 65L. This includes standard backpacks (such as Eastpak, Jansport's, Northface), day packs (Osprey, REI, Gregory), and larger packs (Mystery Ranch, Mountainsmith, Deuter). The Ultralight Ventilation Backpack Frame attaches to framed and frameless backpacks to provide superior airflow.
Carry In Comfort - The Ultralight Ventilation Backpack Frame makes any backpack exceptionally comfortable, spreading carried weight across a soft hexagonal frame that instantly conforms to the user's back. Rough, absorbent mesh padding common in pack design is kept at a distance, preventing chafing and sweat retention.
Improve Your Posture - Carrying a backpack can cause neck stiffness, rounded or uneven shoulders, altered gait, spinal misalignment, and more. By positioning the pack further from the body and supporting it with a flexible frame to disperse dynamic forces, it can be easier to maintain good posture.
Prevent Injury - Frameless backpacks lack a rigid shape and can gradually harm the wearer if overloaded or improperly fitted. The Ultralight Ventilation Backpack Frame adds comfortable structure to any bag, helping to prevent injury by evenly distributing its weight across your body.
Protect Your Gear - Heat, moisture, and bacteria can wear down even the toughest outdoor fabrics. Keep your favorite gear longer by reducing sweat buildup and wicking it away faster with improved airflow.
Ergonomic Honeycomb Design - The frame flexes and contours to your back's shape and movements. It also maximizes your back's exposure to the open air by as much as 90% more than conventional backpack frames. The frame is also designed to correctly wear your backpack and maintain the desired center of gravity.
Heavy-Duty Construction - Our frame is made of High-Density Polyethylene (HDPE), a thermoplastic polymer made from petroleum. It's a versatile plastic used in many applications, such as plastic bottles, milk jugs, shampoo bottles, bleach bottles, and other containers. Also used in piping, cutting boards, and some shoe parts. The frame is strong, durable, flexible, abrasion-resistant, and built to withstand extended use under extreme conditions. We chose this material because it is flexible, comfortable, and can move with your back. The material also doesn't collapse, so the airflow doesn't close off regardless of the pack's weight. We also offer a lifetime guarantee. In fact, we encourage you to put it to the test. If you (somehow, somewhere) break it, we will happily replace it.
Universal Compatibility - A Ultralight Ventilation Backpack Frame can be quickly installed on any gear carried with shoulder straps or harnesses, including backpacks and bouldering crash pads. Don't worry about your height or torso length either: One size fits all, no adjustment required.
Ultralight Design & Portability - Lighter than a pair of socks, the frame weighs just under 3.3 ounces. 15.5" x 8.5" x 1.4" flat.
Safe & Sustainable Material: Vaucluse Backpack Ventilation Frames are made from the same material as milk jug containers. High-Density Polyethylene (HDPE) is FDA-approved and used to make food containers such as milk jugs. Non-toxic, food-grade, and recyclable. Safe for applications that directly impact humans.
No-Mesh or Foam Design - The design uses NO mesh or foam material, which only soaks up sweat and retains heat. This frame minimizes the absorption of sweat and maximizes the dissipation of heat.
Satisfaction Guaranteed - The Ultralight Ventilation Backpack Frame is designed to improve your outdoor experiences.
Lifetime Warranty - If it breaks, we'll send you another. If you don't like it, you can get your money back. It's that simple.
Better Hunting - Sweating less will reduce an animal's ability to smell your presence.

⭐⭐⭐⭐⭐ Reviews from Ultralight Ventilation Backpack Frame customers:
⭐⭐⭐⭐⭐"How much of a difference can the Vaucluse 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!" - Michael L, Rhode Island, Osprey 36L
⭐⭐⭐⭐⭐"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." - Tom P, New Jersey. REI Trail 25 Pack 20" x 14"
⭐⭐⭐⭐⭐"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!"
- Scott H, North Carolina, Hyperlite Mountain Gear Southwest 3400
⭐⭐⭐⭐⭐"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."
- Dave, Alps, California. 75L Jansport Whitaker and 28L Deuter Trail SL
⭐⭐⭐⭐⭐"Loving the Vaucluse Frame! It's perfect for every season. Now, I never ruck without my Frame."
- Max D, day training with a rucksack, Detroit, Michigan
⭐⭐⭐⭐⭐"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.” - Jim Armstrong, 40L Pack, Search & Rescue Operations, Decatur, TX
⭐⭐⭐⭐⭐"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
⭐⭐⭐⭐⭐"Definitely keeps things drier and cooler. I rate the Vaucluse Ultralight Ventilation Backpack Backpack Frame at 100%!" - Joe S, Gregory Palisade 80 pack, California
⭐⭐⭐⭐⭐"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
⭐⭐⭐⭐⭐"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, SKYSPER Hiking Backpack 40L, 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 Newberg, Oregon
⭐⭐⭐⭐⭐"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
⭐⭐⭐⭐⭐"With the warm temps my back didn’t sweat at all…nice! It’s well constructed, lightweight, flexible, and doesn’t feel odd when wearing it." - Mike L, multi-day hiker with a daypack, Tucson, AZ
⭐⭐⭐⭐⭐"I did not sweat as much as normal with the extra space between my shirt and the Ultralight Ventilation Backpack Frame. Felt good and had no gear issues." - Walter S, day hiker with 22L Osprey backpack from North Carolina
⭐⭐⭐⭐⭐"Works well. My back stayed dry on some heavy-duty hikes." - Matt C, 2-3 day hiker with 35L backpack from Pennsylvania
⭐⭐⭐⭐⭐"The Ultralight Ventilation Backpack Frame seems to deliver on its promise. The length [of the Frame] creates a lot of real estate on my back where air can reach. I am very pleased with the performance of the Frame. It is also very comfortable with no discernible pinching or weird rubbing." - Coy S, multi-day hiker with 35L and 60L packs from Alabama.
⭐⭐⭐⭐⭐"It works. I have not experienced sweat on my back. The only area that I get sweaty is at the very bottom where the bag touches my body near the waist area. This is fine as it still significantly reduces the amount of sweat/water-loss by at least 80%." - Aaron S, day hiker with 30L backpack from Arizona
⭐⭐⭐⭐⭐"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 22L backpack from California
⭐⭐⭐⭐⭐"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, 35L 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 with a t-shirt and light fleece jacket." - Tyler F, day hiker with 35L backpack from Washington
⭐⭐⭐⭐⭐"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
