I tried to find one on ebay and no luck so far. I'm thinkin it's custom made, cause that's a really nice shirt. Look how shiny it is in the flash. Probably would't cost more that $10 or $15 to get a logo like that emroidered onto a shirt you already have.
i got a mazdaspeed t for christmas.... orange with mazdaspeed on the front and zoom-zoom on the back. I like that button up shirt though. I'm pretty tiny, too, though.
