Gregory's 3D Hydro reservoir features a patent-pending, soft-molded 3D design that allows it to perform like a reservoir but dry as quickly and cleanly as a water bottle. Its self-supporting, baffled construction dramatically speeds up drying time and discourages bacteria growth, so you can get back out on the trail without worrying about funky water. Other innovations include an integrated QuickDry hanger, magnetic DryLock bite valve, and rapid-mount SpeedClip pack integration system, bringing simplicity and ease of use never before seen in a hydration reservoir.
