Clear as a mountain stream

Nothing tastes quite like crisp, clean water straight from a river or a spring. But to be safe, you still need to filter it to remove particles, protozoa and bacteria like Giardia, salmonella and cryptosporidium.

If you prefer the design of the Klean Kanteen™ Classic bottles but still want to take your Klean Kanteen™ on the trail, just pick up one of these small, lightweight water filter adapters. One end screws into the Classic bottle and the other end has a universal thread design that connects to most standard backcountry water filters.

Fill up your Klean Kanteen™ Classic with cool water straight from the source. Now it will stay fresh and delicious all day because your 18/8, food-grade stainless Klean Kanteen™ doesn't absorb or leach flavors.
