Very warm, but didn't cover my ears all the way.
I thought that this hat was really stylish and had a great lining to keep my head nice and warm for my first ski trip. I think this hat is better for street wear than for ski wear, but I did wear it during the whole ski trip and my head never got cold. I have a nice average sized head and I was looking for something that was going to keep both of my ears covered. It only covered it about half way and I really needed to pull it down on my head to cover them. I still have this hat and still plan on wearing it in the future. All in all, I would recommend this hat.
BTW, I got the white one and it is true white. I loved that!
