The Survivor filter straw turns almost any freshwater source into a safe drink. Its nanofiber media reduces bacteria, protozoa, and sub-micron particulates, so you can sip directly from a stream, lake, or water bottle with confidence. Lightweight and pocket-sized, it belongs in every hiking pack, camping kit, and emergency bag. The fast-flow design means easy sipping with no hard sucking or waiting. Made in the USA and Space Foundation Certified, it is serious filtration in the smallest possible form.
