Klean stands the test of time.
"We bought our first bottles from KK twelve years ago. The kids bottles with sippy lids. I finally passed on about half of the 12 oz uninsulated ones to friends with smaller children. All our larger insulated bottles are still in rotation. We buy new lids every few years and use them a lot. I really like the 32 oz bottle. It’s a good “adult” size for ice and beverage. Hiking, school, workouts , tackles most activities."
