Designed for your waist, hip, or fanny pack, the Platypus Big Zip EVO Lumbar Reservoir makes sure you stay hydrated whether you're on the trail or commuting through town. Built with plastic that is BPA-, BPS, and phthalate-free, you'll notice no faint flavor in your crystal clear h-two-oh, and it carries up to 2 liters of the stuff. The bladder is well-designed, with easy filling and drinking features, as well as a leak-proof shut-off for the valve. A semi-rigid center baffle provides low-profile support, and additionally makes the reservoir easier to clean and dry out.
