Normally, you'd feel the strain being pulled down against your spine but the air bladder helps to spread the weight to your lower back which can support more weight without sacrificing comfort. Since all of the weight in the back pack is now resting comfortably just above the waistline, your body posture is now able to relax in an upright position - as apposed to a hunched over position to compensate for the extra weight.
This shift in body position will allow for less stress on the spine and encourage better posture.
This is a positive solution of a big problem seen in schools across the country which is the negative effects that a heavy bag has on a child's back. Medical studies have proven the AirBac to prevent and comfort any safety issues that arise with a heavy load of text books and supplies.
It's debut at this years Travel Goods Show is not to be taken lightly - no pun intended. The AirBac has entered the show as a truly innovative advancement in backpacks and school bags. Available at most online retailers, the AirBac will be available in stores soon.
See you at the show!

AirBac’s patented air bladder takes the weight off your shoulders and spine, where you’d feel the strain of the load being pulled down, and spreads it to your lower back, which can support more weight without sacrificing comfort. You’ll feel like you’re carrying half the weight.
