Osprey Hydraulics Reservoir

The new 2-liter and 3-liter Hydraulics reservoir is here, featuring a complete redesign. It includes innovative and ergonomic improvements that make it easier to carry, fill, load, and use—whether you're navigating around town, traveling, or hitting the trails. This model also has a lightweight yet sturdy backer plate that prevents bending or buckling during loading, making it ideal for both internal and external hydration sleeves in your pack.
