You know, it's good that he at least skis. If he can't help skiing by his abilities and such he can help it by being the consumer. If he doesn't advertise that he thinks he's hardcore it should be fine. Jiberish is dope and not many people wear it, so if it's only you and him it doesn't matter.
I hear where you're coming from though, I've seen someone in an armada tee, and I expected him to be a skier, so I went and talked to him, and he's like, "no I don't ski, I skied once in grade 7."He can wear it, but it was kind of a let down.
