Expansion pack

The FluidLogic Expansion Pack adds 4L of modular storage capacity to the GPR50 Hydration System with a direct-attach, low-profile fit that stays stable under movement.

Dual side compression pockets hold water bottles, while an internal zippered pocket secures small essentials. Built from durable 600D nylon with water-resistant zippers, it installs and removes without tools. Integrated compression straps reduce load shift while riding.
