I highly recommend these, they're very warm. I used to put these on my child when we weren't going outside. When I put these over socks, they were fluffy and cute, and seemed very warm. Also, although they are not reversible, the back is made of a cute quilted material, so I sometimes put them on inside out. I don't see any noticeable stains, but please be aware that these were worn by a child. Thank you.
