BUILT Cascade 16 oz Stainless Steel Kids Water Bottle with Leakproof Flip-Top Chug Lid, Dark Blue

This is the perfect size for backpack or purse. Twist top to make it easy to clean. Also twist top provides reassurance that a button isn't going to be pushed on accident and have water spilled everywhere. I like this brand, I replace every so often because they get banged up from being dropped (haven't broken tho!). Also replace every so often because you can only clean a bottle so well, there is a rubber gasket that can't come out and tiny crevices that I fear harbor mold. Overall, best I have had

I love this bottle, I am very sorry it's not at our local Walmart anymore, I had to order it. I love the stainless steel inside, and the drinking tip is great. The water stays fresh and taste the same good at the end of the day when my son comes back from school.This is the longest that has survived with him, about two years. All other bottles we had before broke within a few months. This one is the best ever and I'm going to buy it until we get tired of it :-)
