Leave the funky-tasting tablets and UV devices at home. This bottle filters water in seconds to remove pathogens like Giardia, heavy metals, and unwanted flavors without sucking, squeezing, or waiting. Each purifier cartridge can be used 300 times before it needs to be replaced, so you don’t have to worry about running out of filtration in the middle of a through hike or extended trip. Don’t need all out, drink-even-the-murkiest-water hydration? Swap out the purifier for a tap filter.
