From the handle to the hose and baffles to the bite valve, Osprey analysed every interaction and aspect of the Hydraulics design to identify opportunities for a better user experience—redesigning, reshaping and updating to create the best reservoir series yet.

New ergonomic handle
An all-new comfortable handle allows for true one-handed filling. This easier-to-fill design is also easier to carry and pour.

New bite valve
An all-new compact bite valve preserves excellent water flow in a smaller package. Equipped with a new on/off lever that is thumb-operable and easy to regulate with one hand.

New opening design
A brand-new compact Slide-Seal opening allows for one-handed filling, removes bulkiness, slides into packs easier and seals securely. The new HydraClip reservoir attachment seamlessly integrates with this new opening design.

Updated magnet system
All parts in this system, including the magnet, sternum slider and sternum buckle, have been updated to ensure a more secure hose capture.

New hydraclip
An all-new thoughtfully designed reservoir attachment clip that is intuitive to operate and integrates seamlessly with current and past season reservoirs.

New baffle & backer plate
A new centre baffle on reservoirs flattens the profile while carrying the stiffness of the backer plate through to the front panel. This reduces bending and buckling when loading into the pack. Dual baffles on the flatten the profile and improve control when filling, pouring and carrying the reservoir.
