I skied last week in the snow in Utah and by the end of the day the seat of my pants was very wet from sitting on the chair. It didn't soak all the way through to my underwear but it definitely made me colder. When sitting the body warmth would melt things. I just have a pair of shell pants with long underwear not an insulated pair of pants. On snow days I frequently wear a pair of fleece shorts which help out but I forgot them when I was in Utah.
