Took these out skiing this past weekend up in Colorado. Pants worked well.  It was about 5F in the morning when we started and was around 13F by early afternoon. It was a windy day with gusts at 20+ MPH and snowed on us off/on throughout the day. When we first got out of the car and the cold blast hit us, I was concerned I wasn't going to be warm enough so I stopped in the resort on premise store and added a thin base layer as I was not wearing any base layer at all. With only the base layer and these pants, I was fine all day. They worked well to repel water from the snow. Pants fit well and are adjustable in the waist.  The gator on the leg easily fit around the ski boots to keep out snow.  I would certainly recommend them for use on the slopes.
