The flight jacket or bomber jacket is an item of clothing originally created for pilots, which ultimately became part of popular culture and clothing. In the First World War most airplanes did not have an enclosed cockpit, which necessitated an item of clothing that could keep pilots adequately warm. The classic sheepskin designed and manufactured firstly by Leslie Irvin and set up a manufacturing company in the United Kingdom in 1926 and became the major supplier of flying jackets to the Royal Air Force during most of the Second World War.
The two most historical and renowned American flight jackets are the A-2 jacket and the G-1. Not only these two jackets were useful to the serving men who wore them, but in their reputation they became symbols of honor, adventure, and style.
Today flight jackets are usually connected with the MA-1, a U.S. military jacket, which is mostly found in black or sage green.
