Klean Kanteen went back to the drawing board and spent a year developing a new sport cap that delivers some serious flow, the Sport 2.0.

Klean Kanteen's revolutionary Sport 2.0 gets with 3x the flow of their first sport cap and a quieter valve.

If the old sport cap was a tiny, trickling creek, the new Sport 2.0 is Niagara Falls. It's also designed to last, just like our bottles.

The cap fits Klean Kanteen bottles including the Klean Kanteen Sippy. Please note: the cap does not fit wide neck Klean Kanteen bottles.
