Introduced by the mid-1950s the MA-1 became the flight jacket of U.S. Air Force and Navy pilots and ground crew. An addition to the jacket in 1960 was the reversibility to show off an Indian Orange lining. The reason being if a plane crashed the pilot could reverse the jacket to the orange side to signal rescue personnel. Alpha Industries' first government contract for the MA-1 was awarded in 1963. They started producing the MA-1 flight jacket for the civilian population in the 1970s. Slim-fit flight jacket sports a water-resistant flight nylon shell and a nylon lining. Fully reversible.
