Our all-new 3D Hydro Formed Reservoir is the first hydration system that performs like a soft bladder, but fills, cleans and dries like a water bottle. Among other convenience-enhancing proprietary technologies, it features a soft-molded, self-supporting 3D design that prevents contact between the top and bottom layers, dramatically improving drying time and discouraging funky bacterial growth without affecting packability or flexibility. The integrated crescent-shaped handgrip along the top edge prevents the need to hold the top open while filling, and the integrated QuickDry hanger hook allows easy storage and convenient drying after cleaning. A full-length baffle constructed from the same high-strength, taste-free, BPA- and PVC-free Metallocene PE film as the rest of the bladder prevents barreling and sloshing as you attack the trail, and a positive-click SpeedClip hook inside the hydration sleeve of compatible Gregory bags eliminates hassle when installing or removing the reservoir. As if that weren’t enough, the magnetic DryLock bite valve offers quick, one-handed opening and closing with the simple press of a button, no guesswork needed.
