Hey everyone,I've a pretty new snowboarder, only been about a dozen times, but I absolutely love it. When I go riding, I usually wear jeans underneath my snowpants cuz I dont have anything else that can both keep me warm and not get waterlogged. The problem is that everywhere I go I hear I shouldn't wear jeans, but what else can I wear? Sweats have cotton, so that would be worse! The option I see is to buy that under armor stuff, but it doesn't look very warm. I'm a skinny guy, so I need some extra insulation that god didn't bless me with. What do you suggest? what does everyone usually wear under snowpants anyway?
