The Wilderness Technology TPU Hydration Reservoir is a must have companion for any day trip or multi-day backpacking trip. This reservoir features a wide mouth opening for easy filling and cleaning. Another great feature is the insulated hose. When you're out on a really cold or really hot day the insulated hose will help keep the water in the hose an ideal temperature. The hose also features a start/stop flow valve and a cover for the bite valve to keep your bite valve clean.
This reservoir will fit most backpacks that are hydration reservoir compatible.
