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 rucksack range yet. A new generation of hydration reservoirs is here! This version features dual baffles that provide better structure and handling of the hydration reservoir whilst maintaining the lowest possible weight. The hydration reservoir works best in the dedicated internal space within the rucksack. It contains no BPA. Create your own hydration system and supplement it with Hydraulics accessories, such as magnetic kits, quick couplers and drinking valves, which allow easy swapping of the hydration reservoir between packs. An ergonomic handle enables 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, fits onto containers more easily 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 during filling, carrying and pouring.
