Klean Kanteen Water Filter Adapter

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 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. Great product! Note: adapter only, water filter not included.
