For many golfers across the country, cooler weather has arrived, and the ball is starting to fly shorter for a handful of reasons: the ball is colder, your body is stiffer and the air is denser. But one variable that is often overlooked is how extra layers of clothing affect swing speed and distance. Could it be that that the ball flies shorter in part because we are wearing base layers, pullovers and jackets which prevent us from moving?

As part of our MythBusters series, two Golf Digest staffers hit a series of shots wearing different amounts of clothing, measuring swing speed, ball speed and distance. What we found may surprise you.
