Lighten up with AirPacks.
Living in the modern age has its conveniences - and they all add weight. Cell phones, portable CD players, PDA's, MP3 players, and laptop computers have made their way into backpacks and briefcases and are weighing us down. The result is strain on the muscles in the upper body that causes head and neck aches, bad posture, muscle spasms and tingling in hands from carrying too much weight where it shouldn't be carried. At AirPacks, we've developed a unique, patented system designed to help tote today's loads more comfortably and safely. The AirPacks System is an innovative "air technology" that uses a combination of air-filled straps and a lumbar cushion to redistribute weight to the stronger, load bearing muscles in the hips and lower back - exactly where medical experts say weight should be carried.
No more slouching
By shifting weight to the lower extremities, the AirPacks System creates a fulcrum that promotes an upright standing position. Encouraging the body to stand posturally correct, the AirPacks System actually improves the overall biomechanics of the spine, reducing the stress on the body by 80% and lightening the effective load by 50%. So the wearer actually FEELS BETTER.
