Gregory 3D Hydro 3L Reservoir Ocean/Orange, One Size

"What Our Gearhead® Experts Are Saying:""I've been running the 3D Hydro in my Gregory pack for a full season, and the fit is seamless — the Speedclip locks it in place, and the anatomical shape sits flat against my back without any shifting. The full-length baffle keeps sloshing minimal even when the reservoir is half full, which makes a real difference on longer days.""A hydration bladder should be easy to ignore while you're moving and easy to deal with when you're not. The Gregory 3D Hydro 3L Reservoir is built around both halves of that equation. The 3D self-supporting construction keeps the reservoir from collapsing in on itself, which speeds up drying and limits odor buildup between trips. A full-length internal baffle reduces sloshing on the move, and the Drylock magnetic bite valve stays accessible and drip-free on the shoulder strap. Back at camp, the QuickDry Hanger and open construction make drying straightforward, and the crescent-shaped handle gives a stable grip while filling. The Speedclip attachment locks the reservoir into Gregory packs cleanly, and the quick-disconnect hose makes removal simple after every outing."
