Clinically proven to reduce backpack stress.

Airpacks, ergonomic design combines wider shoulder straps and an inflatable lumbar cushion, which when properly positioned in the small of the back, creates a fulcrum to redistribute the weight from the shoulders to the hips, promoting a healthier upright standing posture, enhancing the body's natural ability to properly carry weight. Getting the right fit is very important to realize the AirPacks^® unique ergonomic design benefit.
