The streamlined HydroBak carries 50 ounces, the equivalent of two large water bottles. The over-the-shoulder tube provides easy access and the breathable mesh harness keeps you cool. The HydroBak is compact and has a low profile so it’s stable and out of the way. Plus, it has an external zip pocket for keys and other essentials.
