Finally a pair of ski pants for women that you can MOVE in.I was skeptical when I first received them. The pants are not thick at all. So if you are expecting a thick layer of insulation, you are not going to find that in these pants. That being said, I put them on and went outside in 30 degree weather and was absolutely fine.I don't know how to describe the fabric...it reminds me of kind of a funky scuba suit material on the outside and the inside is a very thin layer of soft fleece material.I am 5'8" and weigh approx 140. It is truly a low rise pant with enough material in the back to cover your fanny when you bend over. The pants came about two inches below my belly button. Waist fit darn near perfect. Length was pretty much spot on, wouldn't really want it any shorter for me.The pants are definitely boot cut, almost bell bottom, but you cannot tell from looking straight on. I think they will fit perfect over a pair of ski boots. The gaiter opening is a little bit large, but again, probably just about right for ski boots.The size was fairly true to size. I normally take a medium in most pants, this pant does not fit completely skin tight on me, so I could fit a pair of tights on underneath with no problem. I just don't know if I would actually need them.If you are a truly curvy gal like me with a little junk in the trunk, this is the best pair of ski pants I've found. Let it snow, let it snow, let it SNOW!
