For keeping water handy on the trail, I’d look at this Osprey Hydraulics 2 L reservoir. It’s the hydration insert for a compatible pack, not a backpack. A lightweight, sturdy backer plate helps reduce bending and buckling as you load it into an internal or external hydration sleeve.
This selection is the 2-liter reservoir in Light Blue. Check pack compatibility, full specifications, current pricing, and availability at Osprey.
