The Cooper A-2 (flight jacket or flying jacket) is a leather jacket, made by Cooper Sportswear, worn by United States Army Air Forces and United States Air Force pilots, during World War II. It was replaced after World War Two by nylon versions of the jacket, though it continued to be worn operationally during the Korean War by World War II veterans called back into service. It was re-introduced by the military just prior to Operation Desert Shield, with a modification to allow for modern insignia on the front of the jacket, and has been in service ever since.
