The Osprey Hydraulics™ LT 1.5L & 2.5L Reservoirs by Hydrapak® are made for adventures where the right balance of weight and performance are critical, with the streamlined designs that make loading them into hydration sleeves 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 Twin-welded chevron baffles that help stabilize their liquid contents and maintain a flat profile. They secure with watertight Slide-Seal™ top openings and have extended Pour Shields that allow for easy filling in shallow sinks and 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.
