The Gossamer Gear Bumster Waist Pack is a versatile, lightweight solution for hikers and travellers seeking convenient, on-the-go storage. This pack exemplifies Gossamer Gear’s ultralight philosophy, weighing just 86g and offering 1.5L of capacity.

Key features include durable recycled Robic nylon construction, a quick-access top opening, two internal mesh pockets for organisation, and a key hook. The discreet, secure back pocket adds a layer of safety for valuables.
