The Air Force Physical Training Uniform (AFPTU), first released on 1 October 2006 consists of shorts, short-sleeve and long-sleeve T-shirts, jackets, and pants. The shorts are AF blue with silver reflective stripes on the legs, a key pocket attached to the inner liner and an ID pocket on the outside of the lower right leg. The T-shirts are light grey with moisture-wicking fabric with reflective Air Force logos on the upper left portion of the chest and across the back. The jacket is blue with white piping and a reflective inverted chevron across the chest and back. The pants are blue with silver reflective stripes on the lower legs. At one point, the jacket and pants were redesigned with a lighter, quieter material that didn't make noise with movement. A line of commercially manufactured running shorts is also authorized for wear.
