Product History
Alpha Industries was founded on the belief that the U.S. armed forces deserved protective clothing that was of superior quality and delivered outstanding defense against extreme climate conditions. From our start in October 1959, the U.S. Department of Defense (DOD) awarded Alpha contracts to produce jackets for American service members, including iconic styles such as the N-3B parka and the MA-1 flight jacket. For the next 40 years Alpha would go on to produce a variety of jackets for the DOD including the M-65 field coat, ECWCS parkas and trousers, and test production runs for items in development. In the 1980s the company started efforts in the commercial market. Today, Alpha Industries is known around the world for its high-quality, military-inspired outerwear. We continue to produce the classic military silhouettes that are core to our heritage, as well as modern innovations in style and function.
