Let me ask you this. Do you have rear pockets? Are they velcro? I have Burton pants too and I sit on the snow to strap in or sometimes just to wait for my friends to catch up. I find the snow is going up into my pockets and the inside of my pockets are not water proof. In the future when I buy pants I'll probably go with no pockets. Zippers in the back would be my 2nd choice. I don't need rear pockets since I don't like having anything in them when I sit down.
