I don't give it much thought, as long it's not a ricky-racer setup with 20 different patches, or all the silly skulls and tribal pattern stuff.

I think the trend in motoclothes was preceeded, and perhaps based upon the branding on other sports gear . .. . this of the wet dream of Addias marketing guys . . . not only large logos on their shoes, but folks will buy warm up gear featuring the brand of their shoes . . . .and tshirts, and wear em in environments that have nothing to do with sport whatsoever . . .
Sounds positively Harley like, doesn't it?
