The bomber jacket is a style of men's or women's coat that was originally worn by pilots of the U.S. Army Air Forces in WWII. The jacket was named after the Royal Air Force, which had been nicknamed "the bomber boys."

The design of the jacket is characterized by a full length zipper, two large front pockets with flaps, and elastic cuffs and waistband so that it fits closely to the body for warmth.

In 1951, after WWII ended, an American company called Alpha Industries began manufacturing their own version of the U.S. Army Air Forces B-15 flight jackets with a brown suede-like cloth lining and tough fabric on the outside to protect against dirt and water damage (made popular by Marlon Brando in "The Wild One")
