MA-1
The MA-1, also called the MA-1 bomber jacket or flight jacket, is an American military jacket developed in the 1950s. It and its predecessor, the B-15, were made for the new jet aircraft, which flew higher and colder, in cramped cockpits, than the propeller aircraft before them.
Definition
The MA-1 was designed by the US Air Force as an intermediate-weight flight jacket for use all year, made of high-quality nylon with polyester interlinings. A pilot could wear it open in warm weather and zip it closed in the cockpit. The original design was set out in the military specification MIL-J-8279, amended by letter as textiles, sewing techniques and cockpits changed: J-8279A, B, C and onwards. The most important revision, MIL-J-8279F, was issued in November 1978; the final revisions, G and G Amendment 1, of March 1988 and October 1990, were for ground crew only, as aircrew moved to fire-resistant jackets.
The MA-1 was made in sage green, the colour of the earlier B-15D. Official versions had a safety-orange lining and were reversible: the inner pockets worked when flipped outside, and the zip had a large pull usable from either side, so that downed or lost airmen could reverse the jacket and show the orange to searchers.
Origin
Before jets, crews wore fleece-lined leather jackets, but leather wet with rain or sweat froze at jet altitudes and was bulky in a tight cockpit. The B-15 was first made in cotton and then in nylon; its wool pile collar, carried over from the earlier B-10, was found to interfere with straps in practice. Nylon, invented before the Second World War and used for parachutes, had not been used in flight clothing until after it.
The first MA-1s went to US Air Force and Navy pilots and crews. They appeared in Europe in small numbers in the mid-to-late 1950s, and in 1963 Alpha Industries won the contract to make the jacket; exports by Alpha and later Rothco spread it far beyond the military.
The colour has its own history. The B-15 and L-2 series had been made in dark blue before green replaced it, and during the Korean War crews often mixed flight clothing from different periods and colours. Green won because it blended into the ground if a pilot needed to hide. During the Vietnam War, servicemen bought commercial camouflage copies of the MA-1.

How to identify it
- Read the label. Military jackets carry the specification number and its revision letter; it dates the pattern.
- Turn it inside out. A reversible orange lining is the official pattern; many fashion versions keep the colour without the function.
- The collar. In our handling, a knit collar is the MA-1's familiar finish; a pile collar points instead towards the B-15.
- Japanese reworks. In our handling, Japanese labels treat the MA-1 as a canvas: embroidered, patched, cut longer or reconstructed. Read what was changed and by whom.
Where it appears in the collection
MA-1s sit on the flight jacket shelf and appear across designer shelves, including a Maison Mihara Yasuhiro reconstructed MA-1, an A Bathing Ape and Alpha Industries shark MA-1 and a Raf Simons Riot patchwork bomber of autumn-winter 2001. For the Japanese makers, see our guide to Buzz Rickson's flight jackets.
