Use a durable backpack that adapts to your needs with the Attitude Supply ATD1 Adaptive Backpack. Featuring a boxy shape, this backpack maximizes internal space while keeping content close to your back even when it’s not full. Additionally, the roll top construction ensures expandability and weather protection. Without any front and side panel openings, no one can access the main compartment while you wear the pack. The U-shaped zipper closure on back panel allows for side access to the pack while you wear it. It also lets the back panel open clamshell style, providing easy access to every compartment even if you roll the top. Furthermore, the top, side, and bottom handles help you grab and carry the pack. The adjustable side compression straps manage the pack’s volume while allowing you to carry extra gear on the outside.
