No more dealing with tablets and specialized brushes to clean your water reservoir. This one has a reversible design that makes it super easy to clean and dry. And the hose removes, too, making cleaning even easier. The Badlands Hydration Reservoir has a sliding top that fastens securely for no leaks while in your pack, yet opens wide for convenient filling. With a design like this, you could even add ice cubes before you hit the trail. It comes equipped with an insulating Hydrafusion drink tube that won't leave the hose freezing up—and you out of water while recreating in the cold.
