The next generation of hydration is here. Completely redesigned from tip to tail, the Osprey Hydraulics™ 3L Reservoir delivers smoother handling, easier filling and improved stability—whether you’re commuting, travelling or heading deep into the backcountry.
This updated model features a lightweight yet rigid backer plate that reduces bending and buckling during loading, making it ideal for both internal and external hydration sleeves. The new Compact Slide‑Seal™ opening streamlines one‑handed filling, reduces bulk and creates a secure, low‑profile seal that slides effortlessly into packs.
A refined compact bite valve, intuitive thumb‑operated on/off lever, and an exceptionally secure hose magnet system ensure fast, reliable hydration on the move. The integrated center baffle maintains a flatter shape for better stability and pack fit, while the new HydraClip hanger provides seamless integration with compatible Osprey packs.
