These are some stellar snow pants!
I picked up the snowboard for the first time this season (in november '12) and have put almost 30day of beginner snowboarding into these pants. They have held up and kept me dry like non other!.
Awesome color (coral) for visibility. I got a size up and am glad I did. They do run slightly on the small side, especially so once you add layers underneath (these are shell, no lining).
These have a waist-cincher on each side, which is way important. With multiple layers on, these fit great everywhere, but are too big in the waist (hence the waist-cincher :).
These have lots of room in the legs, I have never felt restrained. Reinforced at the knees, zipper vents on both sides of the thigh help keep ya cool.
Only complaint I have: when they get dirty, it doesn't really wash away. I washed these one time,as they were gathering some dirt, and they looked pretty much the exact same after a rigorous hand-washing. Oh well, they are uber-functional and comfortable!
