I have used these pants a couple of times so far and I'm very happy with it. They're warm enough for skiing in station at -25C with a base layer and on the other hand, they offer a good ventilation system with the zippered traps on the inside and outside of the leg. Perfect for longs ascents !! I normally wear 30 x 30 pants and the small one is perfect for me.
