If you're an ounce counter, cut the weight and carry the Osprey Hydraulics LT 2.5L Reservoir. Designed with a flat profile and twin baffles, this bladder balances the water load and prevents it from shifting around. The Slide-Seal is watertight and top-opening, offering easy access for cleaning and refilling, while the Pour Shield assists you in refilling from shallow sinks. Offering a steady flow rate, magnetic bite valve that attaches to the reservoir hose, and a Hydrapak® Blaster bite valve, pair this reservoir with any Osprey daypack and jump onto the trails!
