One Green Bottle Evolution Collection Sports Straw Cap

easy to use

My little ones find this easy to use as the sports caps can be too hard for them. I do think there are quite a few bits to clean however I have been using it for nearly a year and have had zero mouldy bits

Really like these caps. Easy to clean, good quality, and they don't leak. Everything you need!

Sturdy and leakproof

Bought this as a replacement for the Klean Kanteen lid on the kids bottle. It seems really study and has been leak proof when chucked in the bottom of a school bag.
