Osprey has carefully considered every interaction and aspect of the Hydraulics system, from the handle through the tubing and dual internal welded baffles to the drinking valve, to further enhance the user experience – refining the design, changing the shape and creating Osprey's best hydration pack range yet. A new generation of hydration reservoirs is here! This hydration reservoir is specially wound for kidney and hip packs designed for it. It contains no BPA. Create your own hydration system and supplement it with Hydraulics accessories, such as magnet kits, quick connectors and drinking valves for easy reservoir swaps between packs. An ergonomic handle allows one-handed filling and makes carrying and pouring easier. A compact drinking valve ensures perfect water flow. The thumb-operated on/off lever on the valve is now easier to operate than ever before with one hand. A compact Slide-Seal opening makes one-handed filling easier, reduces unnecessary volume, sits more easily on containers and seals perfectly. Seamless compatibility with the new HydraClip strap for hydration reservoirs (for secure carrying) in rucksacks. Tubing with an exceptionally secure magnetic system. Dual baffles flatten the hydration reservoir profile and improve handling when filling, carrying and pouring.
