Strong disagree. I am a skater and it's not by chance that skaters started to wear Dickies work pants. Durable materials from blue collar working clothes are mostly cheap (except Carhartt now hehe) and make a difference.
In my experience, Vans has some good shirts as well but it varies depending on the product. Also, skate shops (support your local!) have better (as in more durable) options than bigger stores. If they don't sell skateboard parts, go somewhere else if you live in a bigger city.
