Eberlestock Three Liter Hydration Bladder WXP3L delivers great-tasting water to your parched throat time after time. Designed to fit the hydration sleeve of nearly every Eberlestock backpack, these hydration bladders are essential for long, sustained marches where you don't have time for a water break. Smart design powers these Eberlestock hydration pouches; a Storm Valve makes drinking easier, the bladder itself is BPA-free and features anti-bacterial components. You can fill the Eberlestock 3 Liter Water Bladder from a stream using the wide mouth or from a water bottle or other localized source using the screw top. The drink tube is insulated and covered with a protective weave, so you don't have to worry about this important component springing a leak, and a dirt shield for the drink valve. Eberlestock has designed the three liter version of this hydration system to be compatible with all of their backpacks, except for the X1. For a large-capacity, bacteria free hydration bladder that keeps your water safe, accessible, and delicious, slip the Eberlestock 3 Liter Hydration System into the pack of your choice.
