The unique, soft-molded design of the 2-liter Gregory 3D Hydro reservoir provides comfort and stability on the trail and dries quickly thanks to the integrated hanger.

  • Features

    • Soft-molded 3D design prevents contact between top and bottom layers when hanging open, dramatically speeding drying time and discouraging bacteria growth
    • QuickDry hanger offers a convenient option for storage or hang drying on or off the trail, integrated into the reservoir itself
    • Crescent handle is designed to work with the Gregory SpeedClip attachment system for a one-handed lock-and-go linkage system
    • 3D form and full-length baffle distribute the weight of the reservoir by positioning the water flat against your back for optimal stability and comfort
    • A soft-molded handle on the spine makes filling easy and the co-molded baseplate provides full length support for hassle-free insertion and removal from the pack
    • Inline hose quick-disconnect coupling makes for easy refills without having to unthread the hose from the shoulder harness
    • Push-button on/off bite valve allows for confident, leak-free storage while traveling to and from the trail (magnet accessory included)
    • Rubberized fill port opening with integrated hose locator features inline quick-disconnect and screwcap tether
