I was looking for a light shell pant for backcountry skiing and these are perfect. I have only had them for a couple weeks and have only used them for resort skiing so far, but I couldn't be happier. They are very comfortable. I feel as though they move with my body without straining and are very water repellent. I was in pretty wet conditions in a heavy snowstorm and although my upper body ended up pretty damp, my lower half was completely dry. That being said, they are still shell pants, so if you normally ski in pretty cold conditions, either prepare to layer up (I wear two pairs of leggings, one fleece lined and one not) or go for something more insulated.
