Havent worn them snowboarding, but...
I like them a bunch. The material is seriously the nicest I've ever felt, not plastic-y, plenty of stretch. The fit is really nice, I'm 5'4, 130lbs, ~30in or smaller waist and got a small. My legs are way short so I would have gotten an XS if it existed because they are too long, but that always happens to me. A little bummed on the lack of gaiters, waist adjustment, and only one zip pocket (in front). Hopefully my wallet and socks don't get soaked, we'll see. Its not like anyone is buying these for functionality anyways, right?
