Gregory Pack 3D Hydro Reservoir with its special soft molding design ensures comfort and stability on the trail and guarantees quick drying thanks to the integrated attachment. The custom SpeedClip attachment system facilitates integration into Gregory-compatible backpacks.   Features: 3D QuickDry: The 3D soft molding design prevents contact between the top and bottom layers when left open, drastically accelerating drying time and preventing bacterial growth. QuickDry Hook: A practical storage or drying option when hung along trails or otherwise, integrated into the reservoir itself. SpeedClip Mounting System: 3D Hydro-enabled Gregory packs feature a one-hand Lock-And-Go connection between the reservoir hook and the system. SpeedClip mounted inside the hydration compartment of the packs. Anatomical Fit: The 3D shape and full-length baffle distribute the reservoir's weight by positioning the rain cover against your back for optimal stability and comfort without adding extra weight and bulk. Co-Molded Handle: A convenient soft molding handle simplifies filling while the co-molded base provides full-length support for easy insertion and removal from the pack. Quick Disconnect: In-line quick-disconnect fitting for easy filling without needing to remove the tube from the shoulder straps. Bite Valve with Soft Nozzle and Magnetic Clip: Lever-activated on/off bite valve allows for reliable, leak-free storage both on the way to and from a hike (sternum strap magnet included). EasyGrip Fill Port: Rubberized fill port opening with integrated tube locator for quick in-line disconnection and screw-on cap attachment. Safety Information: Fill with water only.
