Physicians recommend that you or your student carry no more than 15% of ones body weight on their shoulders and backs, yet studies show they are lugging as much as 40% each day. Recommended by the Congress of Chiropractic State Associations and developed with orthopedic professionals, the unique AirPacks System, has been university tested and clinically proven to help students tote today's loads more safely and comfortably.
Our patented, ergonomic air-transfer system, with its inflatable lumbar cushion and wide shoulder straps, redistributes weight from the shoulders to the hips and lower back to promote an upright standing position and enhance the body's natural ability to carry weight. Smart design features include: shoulder straps that automatically adjust side-to-side to help maintain correct ergonomic support, even when using just one strap; adjustable strapping for even more customized fit, three convenient zipper compartments that help organize books, pens, and other necessities (even a handy key keeper), and two side bottle pockets. Made of durable polyester in a variety of popular colors. 18.5" x 12" x 10.5". Capacity: 2600 cubic inches. Mini air pump included.
The Large fits larger-sized middle or high school, college students and adults who are 5' 5" or taller or who measure 17" or more from the top of the shoulder to the natural waist (a shorter person 5' to 5' 5" or shorter torso 15" - 17" might consider the Medium). Measure first, get the right size and enjoy AirPacks relief soon.
