We’ve all seen the car ads with the fine print on the bottom of the screen, (*Professional driver on a closed course). We may not be professional, but we do get to do what we do on a closed course to the public. No cops, no speed limits, only bounded by our own skill and the limits of the equipment! So yes, Closed Course As F*! Compare with the competition, made from soft and rugged Port & Company® Core Cotton Tee that will last!
