"This cap is so much better than the sports plastic cap. So easy to clean."
"Love it with the insulated bottle."
"I like this cap for the looks!"
"Off all the classic caps, this one is my favorite. Love the look of the wood with stainless, love the loop size, and love that it's all stainless at the part that touches the liquid. The loop works great with all carabiner's that I've tried from small to big. It shouldn't go into the dishwasher, but it is so easy to clean that this doesn't bother me. Another winner. ."
"Really like that it is metal so I don't have to worry about black plastics in my water! Will purchase others to cap the other Kleen Kanteen bottles I have."
"Great. Replaced the plastic cap with this plastic free option."
