I need a Recommendation

I need some help folks. I want to buy Mike a pair of cool snowboarding pants for Christmas. Understand he is a 13 year old teenager. They need to be warm and stylish for my fashion plate son. Before I start perusing the various catalogs, does anyone have a recommendation? They don't have to be North Face expensive but they have to deliver cool warmth, if you get the drift of my oxymoron!
