The MA-2 bomber jacket (also known as MA-2 flight jacket or CWU-45 flight jacket) is a version of the MA-1 bomber jacket that was originally designed for the U.S. military during the 1950s. The term MA-2 was a trademark of the Cobles Clothing Company, adopted in the late 1980s when the CWU-45 military jacket started to gain popularity in street fashion. When contested in court, Cobles lost the exclusive right to the use of the term as they had attempted to widen it to other garments and footwear which was not acceptable because of a legal technicality. The term MA-2 has become so popular it is now used interchangeably with CWU-45 to represent this type of jacket.
