Redesigned for a better user experience, the Osprey Hydraulics LT 1.5L Reservoir is a lightweight hydration system perfect for hikers who prefer a lighter setup. It features an all-new comfortable handle for one-handed filling, carrying, and pouring. The compact bite valve ensures excellent water flow and is paired with a new, thumb-operable on/off lever for easy regulation. A brand-new compact Slide-Seal opening allows for one-handed filling, reduces bulk, slides easily into packs, and seals securely. The HydraClip reservoir attachment integrates seamlessly with the new opening design. All components, including the magnet, sternum slider, and sternum buckle, have been updated for a more secure hose capture.
