Osprey has carefully considered every interaction and aspect of the Hydraulics system, from the handle through the hose and dual internal welded baffles to the bite valve, to further enhance the user experience – refining the design, reshaping the form and creating Osprey's best hydration pack range yet. A new generation of hydration reservoirs is here! The 3-litre Hydraulics hydration reservoir, now completely redesigned, features innovative and ergonomic improvements that make it easier to carry, fill, store and use – whether you're exploring the city, travelling or heading out on the trail. This version has a lightweight yet rigid back panel that helps prevent bending and breaking when filling, making it ideal for internal and external rucksack pockets specifically designed for hydration reservoir storage. BPA-free. Create your own hydration system and customise it with Hydraulics accessories, such as magnetic kits, connector valves and bite valves for easy transport of hydration reservoirs between rucksacks. The ergonomic handle allows one-handed filling and makes carrying and pouring easier. The compact bite valve ensures perfect water flow. The thumb-operated on/off lever on the bite valve is now easier to operate than ever before with one hand. The compact Slide-Seal opening makes one-handed filling easier, reduces unnecessary volume, sits more securely on the hydration reservoir and seals perfectly. Seamless compatibility with the new HydraClip hanging hydration reservoir (for secure carrying) in rucksacks. Hose with an exceptionally secure magnetic system. The centre baffle and rear reinforcement panel flatten the profile whilst strengthening the front panel, reducing bending and sagging of the hydration reservoir when stored in the rucksack.
