    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.

      Love it

      Loving the 3L!

      • Familiarity: I've used it several times

      I’ve used 1.5L in the past but the 3L is a total game changer for longer hikes/objectives. Love it!

      Great bang for your buck!

      • Familiarity: I've used it several times

      Great reservoir for any kind of use, clean and very compatible for any pack. It has been great on several hikes and bike rides so far!


      • Familiarity: I've used it several times

      I'm relatively unimpressed after using Hydropak, Camelbak, and Osprey reservoirs. Wanted to try something different, but I will be going back to Hydropak.

      Great reservoir!

      • Familiarity: I've put it through the wringer

      This is an awesome reservoir. Easy to fill and keep clean, and no weird plasticky taste. The bite valve took a minute to get the hang of, but have no issues on the trail with it. The 3L size fits in most packs in the daypack size range, and larger. I would think a smaller day/hiking pack would be a tougher fit for the 3L reservoir just because the size of the pack. To be safe, I would recommend the 3L for packs about 18-20L and up.

      Best reservoir ever!

      • Familiarity: I've used it once or twice and have initial impressions

      easy to use and clean also super easy to dry, it's 3D design helps a lot when it comes to drying it. Highly recomended!

      i like it

        I like it better than my camel bag. I like the plastic reinforcement on the top and the screw lid
