Description
The Arc'teryx PRO Backpack Lid is a detachable, interchangeable storage lid designed for the NoZone PRO 40 and Alpha PRO 50 backpacks. It adds fast-access storage for high-priority equipment while allowing mountain professionals to transfer essentials between compatible packs based on the day's objectives.
