Osprey’s 3-Liter Hydraulics Reservoir is a hydration reservoir for hikers, backpackers, and bikers looking for an intuitive, durable, and safe option for long days on the trail.

Key Features:

• Slide-Seal – Instead of a twist-off cap, Osprey uses a sliding, seal top that is watertight, easier to secure, and provides a wide-mouth opening for filling and cleaning.

• QuickConnect System – The reservoir can be disconnected from the tube, making filling and removing the reservoir quick and easy.

• Hydrostatic Backerplate – The back of the reservoir provides structure so that the pack can slide in and out of a packed backpack without collapsing.
