All of these Klean Kanteen
bottles feature the Sport Cap 3.0
which is "chirp" free, has a 25% higher flow rate than the 2.0 and is leak resistant.
The 18 oz (532 ml) Klean Kanteen bottle is for grown-ups and kids. The compact size makes it easy to carry, lightweight, and even fits the water bottle cage on most bikes. It fits the smaller hands of the younger user.
