I used these pants about 9 days skiing on piste and 2 days ski touring this season (2012/2013).
So far I have been very happy. When touring or on warm days a light, or no, base layer is perfect. On cold days a heavy base layer makes them fine.
I like the idea of water proof lowers and resistant uppers. So far the ide works great.
