The patented HydraPouch personal hydrator is the first beverage container of its kind. Its unique design has been specifically optimized to improve a racer's entire "hydration experience" during a road or trail race. It is flexible and conforms easily to the shape of a racer's hand, it can be opened for filling and refilling with one hand, it has a splash-resistant closure that keeps liquids in even when held by the swinging hand of a runner, and it has an integrated moulded spout so a runner can easily suck or pour out the contents.
