Because they're oakley. People love the O and the image/prestige associated with it. I'm not hating on that either, its just the truth. I've had 4 pairs of crowbars, then i went around and started trying on every pair of goggles i could get my mitts on and I found a pair of scotts that i like much better. To each his/her own though.
Also, who wouldn't want to be like tanner, seth, simon, jon, etc.... They're pretty amazing. It must be the goggles.
I'm certainly uncertain, at least I'm pretty sure I am.
