Why We Like The Gregory 3D Hydro 3L Reservoir

The Gregory 3D Hydro 3L Reservoir is built to be easy to clean and easy to fill, with all the adaptability we need for our biggest adventures. The Hydro is constructed with a soft-molded 3D shape that's self-supporting and prevents the bottom and top layers from folding in on themselves, which promotes a faster dry time and limits bacterial growth. A full-length baffle along the interior of the bladder discourages the reservoir from sloshing around as we hike or bike. Meanwhile, the crescent-shaped handgrip makes for an easy, spill-free filling experience, and the QuickDry Hanger provides effortless storage and drying once we're done for the day.
