Simply find a water source, fill and drink directly through the high-flow, self-sealing nozzle. The filter screws securely onto the flask, doubling as a squeeze filter for filling bottles or pots at camp. The stretch-mesh pouch securely attaches to your pack harness for hands-free use. INSTANT ACCESS Stretch mesh pouch attaches to your pack harness and securely holds the bottle for hands-free hydration. PACKABLE Sized for easy integration with the pouch, the empty PackFlask™ bottle packs small — just flatten, roll, and stash it away.
