Whoever said you can't have your cake and eat it too clearly never had the pleasure of experiencing hydration from the Gregory 3D Hydro Reservoir. Built to serve you as a soft bladder would, but with the easy-to-clean and easy-to-fill adaptability of a hard water bottle, the Hydro features a design that ensures you get the best of both worlds. The Hydro is constructed with a soft-molded 3D shape that's self-supporting and prevents the bottom and top layers from folding in on themselves, which promotes a faster dry time and limits bacterial growth. A full-length baffle along the interior of the bladder discourages the reservoir from sloshing around as you run, hike, or mountain bike. Meanwhile, the crescent-shaped handgrip makes for an easy, spill-free filling experience, and the QuickDry Hanger provides effortless storage and drying once you're done for the day.
