What’s your favorite sippy cup?

Karen

My 18 month old just cracked another sippy on the tile floor. It was a Nalgene grip and gulp, which I loved because it is so easy to clean and didn’t leak. Lookin for ideas for a replacement. I want it easy to clean (as few pieces as possible, no places for mold to hide), durable (for throwing and teething), and actually leakproof.
