Greatest gloves I've ever owned. Absolutely 100% waterproof, Gore-Tex city. I just tested them out in Breckenridge, CO and on Mt. Hood, OR and they are the best gloves for any condition. In Colorado it was sunny and hot so I removed the liner completely and wore just the shell but when I got up to 15 degree Mt. Hood, OR I wore the thinner liner and never got cold at all. I have yet to use the thicker liner just because it's so warm. I'll save it for whenever it gets below zero. You can actually wear both liners together but it's a lil tight. Whatever you do though, make sure you order 1 size up from the sizing chart. The sizing chart said I was a medium, so I got a Large and they fit perfectly or as Ace Ventura would say, "Llllllike a Glove!"
