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 you're several days into your thru-hike and hydration has become an essential part of your routine, you'll be glad you opted for the Hydraulics LT 2.5L Reservoir. By shaving off several ounces—but not compromising on capacity—this is a choice hydration carry for the savviest of long-haul trekkers. Additional optional accessories, such as the QuickConnect Kit, can help you speed up the refill/filter process.
