Staying hydrated is an important part of day-to-day life, especially for those who like to get outdoors and be active. Hikers often have difficulty carrying around enough water to sustain them on their trips with bulky bottles taking up too much room. With the Hydration Backpack - Pack of 10, customers can carry water on their backs to easily sip from as they go about their adventures. It wears like a backpack and has a bladder in the back to store the water. The straps are breathable, lightweight, and adjustable to ensure the comfort of each wearer.
