there used to be this guy at my mountain when i was younger who just wore carharts. i think it only worked for him because he was so god damn good. he won every contest our mountain had like 2 years in a row.
i hope you are not talking about wearing carhartt jeans skiing but their coats are real legit. Here is a link to their streetwear. http://www.carhartt-streetwear.com/
only if you work in purhoe bay drilling oil and wear your work gear on the ski hill when your at home, because its the only outerwear you own. then, and only then is it cool to wear carharts skiing.
