The ma-1 or bomber jacket was first developed in the mid-1950s. The ma-1 and its predecessor, the b-15 flight jacket, were needed at that time because the emergence of the jet age created new requirements for pilot performance, safety and comfort. The jacket was warm enough when flying in cold temperatures. An ma-1 mid-weight nylon jacket is water/weather resistant. The ma-1 navy fighter pilot jacket was the first military flight jacket to cross over into civilian fashion. Our nylon flight jacket includes a knit collar, cuffs and waistband, as well as a heavy gauge brass zipper with storm flap for warmth. Our ma-1 jackets are reversible to bright orange, making them ideal for rescue missions and other times when visibility is imperative. This current version has been kept as close as possible to the classic specifications, which debuted in 1950. In 1963 the jacket received substantial revisions by changing the lining to bright orange and making the jacket reversible.
