Currently I cross country ski with my wife. We both wear a non-cotton base layer, with a fleece top, followed by a LL Bean ski jackets and just nylon water resistant wind breaker pants. I have a nice pair of water proof ski pants that are in great condition, though the waist some how seems to have shrank, since I last wore them in high school over 14 years ago. So I guess here is the question(s).
1) Get a water resistant insulated ski pants/bib? (~$50 )
2) Wear what we currently wear for XC skiing, but add fleece pants (already own)
3) Purchase waterproof pants (~$100+)
That being said, have have never had an issue with being cold or wet w/ our legs when XC skiing. Though we only fall a couple times, if we do fall and we don't have to stand in line or sit on a cold chairlift seat. I was also thinking about scotch guarding the bottoms of the legs and the sides of what we currently wear.
Thanks in advance,
