We wanted to let you know about the latest thing in laptop backpacks. We are carrying more things in our backpacks than ever before. The addition of electronics has made these backpacks a weight issue that could lead to back problems. AirBak is the only back pack that we know of that does this. The come in lots of styles and colors and are reasonably priced based on the long term savings you could have by using them. If you think about it all of the weight in the back pack is now resting comfortably just above the waistline, your body posture is able to relax in an upright position – as opposed to a hunched over position to compensate for the extra weight. There are approximately 21,000 backpack related injuries were treated every year.
