The ‘Climate Lock’ technology in Klean Kanteen products guarantees exceptional thermal insulation. Drinks in such a vessel remain cold for up to 100 hours and hot for up to 30 hours. A new dimension of functionality for all your adventures.

The TK Closure™ system is based on a thread with an internal design called TK, which minimises temperature loss and improves thermal insulation. Thanks to the precise fit of the components, it increases the tightness of the closure and makes it easier to pour drinks without the risk of spillage.
