Smart tip! When you buy a Sports Cap also, you can switch out the tops, allowing it to grow with your child or for others to use.

This sports cap fits all of the classic Klean Kanteens (NOT the wide mouth ones). 
It can be used to change the Klean Kanteen sippy into a drinking bottle for older ages.
