Very warm. Warmer than my Arc'Teryx Alpha SV glove. Same amount of waterproofness but I do feel like they get heavier than the Alphas when wet. The versatility of a glove with the warmth of a mitten, can't go wrong with these.Fit: True to size.Use: Anything that exposes you to moisture and cold.Recommended: Yes. Very much so.Complaints: Can get a bit too toasty?
