If the jeans are waterproof then they should be aight to ride in. I just bought the new Burton Grail Denim Gore-tex jacket and have recently worn it riding the motorbike in the rain and I must say that the jacket kept me dry as a nun on Valentine's day. I'll be rockin it this winter season in NZ. So I'd say that if you wanna cop that style and look fresh it wouldn't hurt to try 'em out. And for looking like a beginner wit dem jeans......n**ga please!

My brother has a pair of dc henshaws and they actually looks pretty dope. Not real jeans thought just looks like it. I would rock them works just like any other snow pants.
