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. When water access is plentiful, reach for this lightweight Hydraulics LT 1.5L Reservoir to cut a few ounces. Ideal for smaller carries and shorter visits to the backcountry, this hydration system is meant for hikers who prefer to maintain a lighter setup.
