Gore-tex is where it's at! I've never had material like this. It's incredible! I did a full day and night pass at a local resort here. It was sunny and beautiful. The gloves were extremely warm, and never let up one bit. After taking a wee break, I hit the slopes again at night. The gloves had moisture on the outside, which froze them up solid. However, this is all external folks! The interior never let up one bit, and I never got any water in my gloves! Just incredible! The cinch system is the best I've ever seen, and the easiest to deal with when without all your fingers. These Mitts are for you, so get 'em!
