Some people think dirt racers are just a bunch of country hicks.  They have no idea how much high level engineering goes into everything we race... from karts to sprints.  Teach somebody a math lesson with this Heavy Blend™ 8 oz. hoodie featuring the joke on the back and and your choice of logo on the left chest and sleeve.  Our hoodies are made from super warm, 50% Cotton / 50% Polyester, preshrunk fleece using Air jet yarn for a softer feel and no pilling.
