The Gregory 3D Hydro Reservoir 3L in Optic Blue is a state-of-the-art hydration system designed for outdoor enthusiasts seeking convenience and performance. Its soft-molded 3D design ensures the reservoir maintains its shape, preventing contact between top and bottom layers, which significantly speeds up drying time and reduces bacterial growth. The integrated QuickDry hanger allows for easy storage and efficient drying, whether on the trail or at home. Equipped with the SpeedClip mounting system, it offers a one-handed lock-and-go linkage with compatible Gregory packs, ensuring a secure and hassle-free attachment. The anatomical fit, achieved through a 3D form and full-length baffle, distributes weight evenly by positioning the water flat against your back, enhancing stability and comfort during your adventures. Additionally, the soft spout bite valve with a magnetic clip features a lever action on/off mechanism, providing leak-free storage and easy access to hydration on the move.
