Sheldon B.wrote a review of Marmot Expedition Mitten - Men's on December 31, 2018
I've skied with these a couple of times in cold weather. I always use inserts with mittens but some I've had in the past still weren't warm. Not the case with these, very warm and comfortable, easy on and off if you have to use your fingers. The only negative I have is the palm material is too slick and items can slip out of your hand without a tight grip.
