I haven't tried them on on a cold day but I really like the mittens. I received another pair a few days ago and although they were XL sized they were too small (and my hands aren't that big). It is great! I ordered men's XXL mittens and they have plenty of space. They are also quite long on the arm so they can be worn over my coat. I like that there are no separate finger areas. When my hands are cold (hope not) I like to move everything together including my thumb to keep each other warm. I can easily do it in these. Other reviews say they are warm so I trust that but they feel warm and I like the other features and size. Will update if they aren't warm otherwise I assume they will be.
