The Arc'teryx Scorpion pant is made with Gore-Tex Softshell, and as such, are completely water-proof and breathable, not water resistant like it says here. In addition, the high-loft fleece inside adds insulation, without being bulky and "puffy" looking. I've got the men's version, and they will keep you dry in the worst snowstorms, and I usually wear a thin baselayer, or add light fleece pants, if it's really cold.

The Scorpion pants are my favorite skiing pants - practically waterproof, warm, yet breathable. I always turn to these pants whether I'm heading into the backcountry or just playing in the resort. I was worried about the lack of venting zips, but they breathe so well there isn't a need. They are simple in design, yet high in tech features. They are worth the price.

I love these pants. Since they're Arc'teryx, I expected them to be warm. But, I was surprised how comfortable they are - and they're long enough. I do wish they had better-placed pockets, however.

These pants are really well made. They are quite light weight and thin, but super warm and waterproof. These are the first pair my wife has owned and she is very excited about them. Well worth this great price!

After getting sub-par brands I sucked it up and got these and am so pleased. They are your usual ARC smallish sizing. I'm a size 2 to 4 and I went with the small so I'd be comfy with my layers on underneath. the XS was pretty tight for me but I curvy, if you're a straight athletic build and a size 2 the XS would probably be fine. Anyway, they are pretty much waterproof with the Gore-Tex Soft Shell and I stay warm with the soft fleece lining even skiing in -5 F temperatures with good merino underneath. I actually get TOO warm in them if I have thicker layers on but they are awesome. I think touring would be too hot in these in the backcountry but for resort skiing and shorter hikes I'm totally fine in these and the construction is so much better than my crappy old ski pants. These don't rip and they are just bomber. I wish Arc'teryx made petite pants, being 4'11'' mine are so long that when I take my ski boots off I have to roll them up to wear with regular winter boots.
