One Green Bottle Classic Collection Sports Straw Cap

Perfect

Bought these lids to go with our Kid Kanteens - leakproof, easy for little kids to open, do the job perfectly. And I appreciate the eco-crendentials of the OGB company. All good!

Leak proof

We love these lids for our Klean Kanteens (we now have 5!) as they're leak proof and easy to clean in the dishwasher. Knocked one star off as the range of colours is only ok - the brighter/more interesting ones are often out of stock and there seem to be a lot of shades of grey...

Leak proof. Perfect for little hands

Fits kleen kanteen sports bottles. Both the adult ones and the kids ones. 2yo kid uses it independently. Easy for little ones to open and close. Leak proof. I changed all KK sports caps to these ones.
