Current favorite waterproof mittens for toddlers and preschoolers?

We had our first snow storm this weekend and I realized I can’t find my 4 year olds waterproof mittens and the almost 2 year old never had them. I didn’t like the missing ones anyway, but both went out in the snow with the cheap carters knit ones, so time to get some more.

Easy to put on, hard for little fingers to take off, and keep hands warm and dry. Preferably cheap because they don’t play in the snow THAT much (like at school they hardly seem to play outside after it snows even though they say they do).
