Osprey Hydraulics 3L Reservoir

The next generation of reservoir is here.

Redesigned from tip to tail, the 3-liter Hydraulics reservoir features innovative and ergonomic improvements that make it easier to carry, fill, load up and use-whether you’re buzzing around town, travelling or hitting the trails.

This version features a lightweight yet sturdy backer plate that helps reduce bending or buckling while loading, making it ideal for internal or external pack hydration sleeves.
