I wore these babies up at Crystal Mt (WA) last weekend during a pretty cold windy day, (~20 deg F). My hands stayed warm for most of the day, but near the end of the day they started to get a little cold. The gloves have a leather palm and once that got saturated there was definitely more heat loss/transfer through that area. The wet leather palm also wanted to stick to the metal on the chair lift and when I'd pull away it would leave a little of the leather behind. That minor issue aside, even with the palms being wet my hands stayed super dry for the whole day and given the amount insulation the glove has surprisingly warm. I'd say these gloves are best suited for days when its 25 deg F or warmer and they'll definitely be killer in the spring time. Overall a great purchase, I'm happy I bought them.
