Ideal for long days or even weeks out on the trail, the Osprey Hydraulics 2L Reservoir is built to keep hydration simple, reliable, and always within reach. Designed for hikers, backpackers, and outdoor adventurers, it combines lightweight performance with practical features that make staying hydrated effortless from start to finish. The innovative HydroStatic Backerplate helps maintain a flat, anatomical shape while making it easy to slide into a fully loaded pack.

Refilling and maintenance are straightforward thanks to the wide Slide-Seal top opening, while the Pour Shield helps reduce spills when filling from taps, streams, or camp containers. On the move, the Magnetic One-Hand Bite Valve keeps the hose secure and accessible, providing smooth hydration whenever you need it. Built from BPA-free, phthalate-free, and lead-free materials, it delivers safe, fresh-tasting water in a remarkably lightweight 200g package.
