The Osprey Hydraulics™ 2L & 3L Reservoirs by Hydrapak® are ideal for large volume backpacks and extended adventures, with a careful design that makes cleaning, loading and staying hydrated easy. All their parts are BPA-free, phthalate-free and lead-free while meeting the standards of food safety regulations by the FDA and EU. Osprey designed these reservoirs with HydroStatic™ backerplates that provides structure while maintaining a flat profile for easy loading into a full pack. They secure with watertight Slide-Seal™ top openings and have extended Pour Shields that allow for easy filling in shallow sinks and more controlled pouring. Magnetic Bite Valve clips attach to reservoir hoses and magnet sternum straps on backpacks, and the Hydrapak® Blaster™ bite valve offers fast and smooth water flow with a ¼ twist on-and-off switch.
