Have use these pants from 6 degrees up to 30 degrees so far in the Cascade mountains in Washington. Incredibly happy with the pants aside from a few things. They look unique and have some stretch but not very much. They're pretty flattering and don't give too much of a boxy look at all. Me: 5'0, 120lbs with an athletic build, I got an XS. FIT: The waist was too big and the thighs definitely were tight on me, length wise I couldn't have asked for any better as a petite person. If you have muscular thighs or expecting to layer a lot (since these are NOT insulated), I'd recommend going up a size. Also, they're EXTREMELY tight around my snowboard boots (Burton, sz. 7.5)- it always takes a bit of a tug to fit. If you're willing to, you can leave the zippers up for more room but they will end up rubbing when you walk around. QUALITY: The material isn't like other snowboard pants, it has a waxy canvas texture but I really love the look and I don't sound like I'm wearing track pants like a lot of others *swish* *swish*. Waterproofing didn't seem to stand up to other pants of the same rating, definitely disappointed with that-- but not a deal breaker since I haven't been in too wet of conditions and it was just barely coming through after 6-7 runs. Also, the back pockets are useless. Like most girl pants, you can't fit much into them aside from a credit card sized FLAT object. And if you have to dig around in there, the zippers will rip up your hand. Because of the tightness on my thighs I can't really use the front pockets. Keeping because I wanted to give them a chance and used them, but I wished I exchanged/returned TL;DR - Great looking pants, not many bells and whistles, runs small.
