The next generation of Osprey Hydraulics® Reservoirs has arrived, featuring innovative updates that make filling, carrying, and loading smoother than ever. Available in 2-liter and 3-liter capacities, this new design integrates ergonomic improvements from top to bottom for faster setup and more reliable performance on the trail, in town, or on the road. A lightweight yet rigid backer plate adds structure to prevent bending or buckling during loading—perfect for internal or external pack sleeves—while a center baffle maintains a low-profile shape and balanced weight distribution. The Compact Slide-Seal™ opening simplifies one-handed filling and ensures a secure, leakproof seal, and the thumb-operated bite valve offers effortless, controlled flow with every sip.
