Built for long days on the trail, the lightweight Pioneer is the ideal medium to large capacity water storage and delivery system for backcountry group adventures. Two piece construction features a removable water storage reservoir and an abrasion resistant outer sleeve. The reservoir's wide opening is quick to fill and closes tight with a slide-seal top. Nylon drawstring cords make it easy to hang or carry and the new dispensing tap is ideal for filling bottles and washing cookware at camp. Lightweight and packable, it folds down small into its outer shell, an integrated storage pocket stores your hydration accessories when not in use.
