AirBak Transporter Ergonomic Backpacks & Laptop Backpacks
I always carry a ridiculously heavy backpack, but AirBak has saved my back. It has an air pocket in the lumbar area that puts more of the weight on your butt and helps you slouch less and feel less weight on your shoulders and spine.
Perfect for the backpacking man (or woman) in your life...complete with hydration pack, lumbar supporting air chamber, and enough storage and organizational compartments to satisfy pretty much anyone.
These may not be the most feminine backpacks, but they are full-featured, ergonomically friendly, and they come with hydration packs...so they're very functional.
It has AirBak's patented lumbar air chamber coupled with a Camelbak-style hydropak. What more could you want in a backpack for sports?
