Let gravity take its course, and do the filtering for you with the Katadyn® BeFreeTM Filter. Ultra-durable, collapsible reservoir lets you take advantage of smash, stash and go convenience for easy transport in a pocket or pack. At the next available watering hole, simply remove the top, dunk it into the water source, place the filter/cap back on, swish and drink. It's that easy! Drink directly from the reservoir, or use it to refill another bottle.
