From the handle to the hose and baffles to the bite valve, we thought through every interaction and aspect of our Hydraulics design to identify opportunities for a better user experience—redesigning, reshaping and updating to create our best reservoir series yet. Ideal for long days or weeks out on the trail, this larger volume Hydraulics 2L Reservoir keeps the water flowing smoothly. A magnetic, one-hand bite valve keeps water close by. Equipped with a backerplate to create a low/wide profile, there's no need to awkwardly shove your refilled reservoir back into a full pack.
