The Osprey Hydraulics LT 1.5L reservoir is designed to be lightweight and easy to use. The unique combination of the pour shield and Slide-Seal top-opening allows you to easily fill and empty the reservoir, whilst enabling complete access for cleaning after use. The twin-welded chevron baffles provide stability, maintain a flat profile and keep the liquid under control when you're out exploring rough terrain. The bite valve is magnetic enabling easy stow and access to water on the go. When not in use, the bite valve also incorporates an easy on/off twist lock system. Built from strong yet light TPU material, which is designed to withstand either freezing or hot water. The QuickConnect system allows you to remove the reservoir for easier loading, replacement and cleaning.
