Definition of A-2 jacket

The Type A-2 leather flight jacket is one of the most classic and immediately recognizable articles of military clothing ever designed. It is most closely associated with World War II U.S. Army pilots, who often decorated their jackets with squadron patches and elaborate artwork painted on the back. Sometimes casually referred to as a "bomber" jacket, its original designation was "Jacket, Pilot's (summer)," and its wartime usage was limited neither to pilots nor to bomber crews.
