The mark consists of the configuration of a backpack having a vertically-oriented and somewhat rectangular shape. Near the top of the front of the backpack is a pocket with a hook and loop surface in the shape of a semicircle. Below this pocket are four horizontal bands of webbing with a vertical zippered pocket on either side. Two vertical bands of webbing extend upwards from the bottom of the backpack. Four horizontal bands of webbing appear on the right side of the backpack. A large handle extends from the left side of the backpack to the upper right portion of the backpack. The overall rectangular shape of the backpack, shield-shaped design on the front, the pockets and straps on the lower left and right sides, and the zipper pulls are shown in broken lines to show positioning and form no part of the mark.
