Help prevent back injury by lightening the effective weight of your load with AirPacks System packs. These packs use a patented, ergonomic air transfer system, with its inflatable lumbar cushion and shoulder straps, to redistribute weight from the shoulders to the hips and lower back, promoting an upright standing position. By enhancing the body's natural ability to properly carry weight, the AirPacks System reduces stress on the body by 80% and lightens the effective load by 50%.
The Medium #4300 features a new built in padded compartment that can accommodate a standard sized laptop computer. The Medium is designed to fit any larger-sized elementary school, average-sized middle school, high school and college student or adult who is 5' to 5'5" tall or whose body measures between 15" and 17" from the top of the shoulder to the natural waist. Physicians recommend that students carry no more than 15% of their body weight on their shoulders and backs, yet studies show younger students are lugging as much as 40% each day. Standard ergonomic design features include: patented lumbar air cushion and wider, foam cushioned shoulder straps, adjustable both top and bottom with unique slide strapping that automatically adjust side-to-side to help maintain correct ergonomic support. Additional features include: padded haul handle, built in padded laptop compartment, a large interior compartment for heavier books and other necessities, a large front pocket with organizer for notebooks, pens and pencils (even a handy key keeper, CD player pocket and headphone port), a front zipper pocket, and a new detachable cell phone/mp3 holder.
Ideal for middle school students, the large AirPacks System helps students tote today's loads more comfortably and safely.
