great down to mid 30's
These gloves fit well according to the size chart and the quality is pretty sweet. I cannot wear them in temps below the mid 30's w/o several fingers going numb. I imagine if you buy them large and use liners they would be better. My experience is they are a fantastic mild winter day glove, but not for brutal winter days.
