This adult hydration backpack by Camelbak is great for outdoor sports.  Perfect for running, hiking, cycling, skiing and snowboarding!

Camelbak uses materials that exceed the performance and safety expectations of their diverse users. They test- and retest- at various stages of the manufacturing process to ensure the product (and the materials it's made from) works the way it should in worst case conditions like bone-chilling cold, desert-hot heat, and prolonged exposure to the elements. And of course, it should go without saying, their products meet or exceed FDA and EU regulations.
