Designed for easy on-trail sipping, the Gregory 3D Hydro 2-liter hydration reservoir dries quickly, attaches easily to compatible packs and feels comfortable thanks to an anatomic fit.

  • Features

    • Soft-molded 3D reservoir design prevents contact between top and bottom layers when hanging open, dramatically speeding drying time and discouraging bacteria growth
    • 3D form and full-length baffle distribute weight by positioning water flat against your back for optimal stability and comfort without adding weight or cylindrical bulk
    • Integrated hanger makes it convenient to store or easy to hang dry—on or off the trail
    • A soft-molded handle on the spine makes filling easy; the co-molded baseplate provides full-length support for hassle-free insertion and removal from the pack
    • Inline quick-disconnect fitting makes for easy refills without having to unthread the hose from the shoulder harness
    • Lever action on/off bite valve with magnetic clip allows for confident, leak-free storage while traveling to and from the trail (magnet accessory included)
    • EasyGrip rubberized fill port opening with integrated hose locator and screw-cap tether
    • Compatible with 3D Hydro enabled Gregory packs featuring the SpeedClip hydration mounting system
    • SpeedClip mounting system offers one-handed, lock-and-go linkage between the reservoir hanger and pack hydration sleeve
