Increase airflow

True separation between your back and backpack enables massive airflow and superior ventilation, making sure you stay cool and preventing your shirt from building up sweat patches on your back.

Improve posture

By shifting the backpack slightly off the back, the VentaPak makes your straps approach your shoulders more horizontally, gently tugging them back. This effect, coupled with the mesh pressing into the lower back, improves posture and ergonomics.

Reduce back strain

VentaPak’s frame and mesh distributes backpack load more evenly across your back, like a high end mesh backed chair. This keeps your backpack from pressing and digging into your arched spine and straining it.

"...kept my shirt dry and fresh throughout the day!"

In my 5 years of using a bicycle for my main mode of transportation in New York City, I wish I’d had a VentaPak because having sweaty back was all too common a thing. If I had had the VentaPak, it would’ve kept my shirt dry and fresh throughout the day! An added bonus is that it helps keep your backpack nicely aligned in the center of your back whereas my other backpacks would slide side-to-side on my back when I would stand on my pedals to go up bridges, throwing off my weight. This design creates a snug fit with plenty of airflow so your pack stays in place and you don’t get overheated. I love it!

"Same concept as on my giant 40L high end camping/hiking pack"

Its great for day hikes. Needed to get my pack off my sweaty back. Same concept as on my giant 40L high end camping/hiking pack.

"I would recommend this to anyone suffering from neck or lower back pain"

As a physical therapist, I always see people hunched over as they carry their backpacks on their commute. The VentaPak is great as an ergonomic aid - as soon as you put it on you can feel how it prevents your thoracic spine and shoulders from rounding forward when in standing postures. It's also very comfortable! I would recommend this to anyone suffering from neck or lower back pain that has to wear a backpack daily.

"I use this everyday for reduce the strain on my back"

I can't express how great the Ventapak is. I use this everyday for work, and it has helped a great deal to reduce the strain on my back. The weight distribution is great. It also helps a lot on my posture, straightening out my back. The airflow is great and keeps me cool throughout the day. I also have used this product for when I am grabbing groceries, or riding my bike around New York City on the weekends. I can have a load of groceries in my bag, and it feels like the weight is reduced so much. It is very easy to take on and off. Highly recommend this product !


"...attaches quickly and seamlessly to my own backpack"

When I had a chance to try the VentapPak, I was sold immediately. It attaches quickly and seamlessly to my own backpack, distributing the weight better and making it noticeably more balanced and comfortable. Promotes the continued health of my back, too. Thanks, VentaPak — we needed this clever, elegantly simple device!

"This is a must have, here's posture!"

As a gardener, I frequently use a backpack leafblower, as a hiker I always carry a backpack. This is a must have, here's posture! Yes my back is no longer drenched in sweat, but it's my posture that impresses me the most. No more hunched over or juggling the weight, ventapak not only decreases sweating, it distributes the weight while supporting good posture. This is a must have for thru hikers & landscapers, actually anyone who wears a backpack.


"It’s perfect...less sweat and much drier to any destination"

Got this for sweaty back when cycling. It’s perfect and simple setup. good for regular walks, hikes, anything. less sweat and much drier to any destination. Will buy again for different everyday use backpacks.


"This is the best backpack secret out there."

So easy to attach and now my my tennis racquets are off my back and my bike ride is breezy. Freedom! VentaPak is the perfect gift for tennis players! Who would have thought?! This is the best backpack secret out there. Looks durable, stays in place and yet the mesh on the back is so comfortable. I adjusted for just my size. Glad I found this.


Comfort. Convenience. Ease.
