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

This is our 5th bottle so far! We are adults and love to put our filtered water in the fridge, and this is the perfect size for that. My husband requested a 3rd because 2 wasn't enough. I have 2, but I am thinking of getting another. A side note, my toddler ran over one of mine with a convertible power wheel, and it only had minor scratches and scuffs. It made it through the destruction, and that's a keeper in my book.
