If it was physically possible to get them pulled onto my toddler's hands I am sure they would keep her plenty warm, but the long wrist sleeves are so tight and nearly impossible to pull over my daughters hands that these are useless to us. The mittens themselves are huge for the size of her hand, but the wrists are so tight you can't even get them on your child. We threw them out. What a wasteful poorly designed product. I'd rather put two pairs of cheap mittens over her hands at the same time.
