Gregory 3D Hydro 3L

The Gregory 3D Hydro 3L Reservoir is a soft-molded hydration solution designed to sit comfortably and securely in a compatible pack. Its anatomical shape distributes water flat against the back for improved stability, while the full-length baffle avoids the bulk of a cylindrical reservoir.

Integrated SpeedClip mounting, a QuickDry hanger and a soft spout bite valve make it practical on and off the trail. The quick-disconnect coupling simplifies refills, and the 3D QuickDry design helps the reservoir dry faster after use, making it well suited to hikers and other trail users who value convenient, low-maintenance hydration.
