Platypus Big Zip LP 3L Hydration System

Easy to fill and comfortable to carry, the Big Zip LP 3L Hydration System from Platypus offers hands-free hydration for biking, trekking and everyday use. Cleaning and filling the BPA- and phthalate-free reservoir is easy thanks to the wide zip top, and the Slidelock closure system keeps it sealed while in use. The hose pops off simply with the quick-disconnect port, and the high-flow-rate bite valve can be shut off with a quarter-turn to prevent leaking. A baffle down the middle spreads the weight of the water evenly across your back for comfort, and the reservoir fits any backpack's hydration bladder pocket.
