The sport drinking cap offers an option for drinking one-handed and on the go. With the loop cap, you can attach your Kanteen to just about anything. Or you can opt for the low-profile flat cap. For the wee ones, our adapters and Sippy spouts from Avent™ convert the 12oz bottle into a Klean Kanteen Sippy.

All our caps are interchangeable between bottle sizes and are made with polypropylene #5. If you want to go all stainless, choose the stainless steel version of the flat or loop caps.
