Thanks to it's soft molded 3D design, the 3d Hydro reservoir works like a reservoir and dries like a bottle. Add in the SpeedClip attachment system, integrated hanger and drylock magnetic bite valve and you have a one-of-kind solution.k.

• 3D QuickDry: Soft-molded 3D design prevents contact between top and bottom layers when hanging open, dramatically speeding drying time and discouraging bacteria growth.
• QuickDry Hanger: A convenient option for storage or hang drying on or off the trail, integrated into the reservoir itself.
• SpeedClip Mounting System: 3D Hydro enabled Gregory packs feature a one-handed lock-and-go linkage between the reservoir hanger and the SpeedClip system mounted inside the packs hydration sleeve.
• Anatomical Fit: 3D form and full-length baffle properly distribute the weight of the reservoir by positioning the water flat against your back for optimal stability and comfort, without adding weight and cylindrical bulk.
• Spine Co-Molded Handle: A comfortable, soft-molded handle makes filling easy, and the co-molded baseplate provides full-length support for hassle-free insertion and removal from the pack.
• Quick Disconnect: Inline hose quick-disconnect coupling for easy refills without having to un-thread the hose from the shoulder harness.
• Soft Spout Bite Valve with Magnetic Clip: Lever action on/off bite valve allows for confident, leak-free storage while traveling to and from the trail (sternum strap magnet accessory included).
• EasyGrip Fill Port: Rubberized fill port opening with integrated hose locator for inline quick-disconnect and screwcap tether.
