To get at the stuff you're carrying in your backpack, you have to take off your backpack. This is one of those unavoidable facts of life. Unless you're Stretch Armstrong. Or you're wearing a Paxis.
The brainchild of Paul Vierthaler, Paxis is a backpack that look like any other, but with two compartments for storing things. The top one stays in place. The bottom one, however, is mounted to an articulated arm. Pull a tab on the pack's front side and that compartment swings around to the front of your waist, providing easy access to its contents.
