Best Boardin pants out there!
I got the burton AK snowboarding pants last year and they have net let me down. If you have a few extra dollars to spend to get the AK series gear it is WORTH it. I never had to layer with these pants. Just throw some shorts on underneath and go. I stayed completely warm and dry in some of the coldest and windiest days up at Snowbird Resort in Utah, and trust me, IT was cold.
