A men's aviator jacket, also known as a pilot jacket or bomber jacket, is a classic style of outerwear that was originally designed for pilots during World War I. It has since become a popular fashion item for both men and women. Aviator jackets typically have a distinctive design characterized by a cropped length, a front zipper closure, a ribbed collar, and ribbed cuffs and hem. They are often made from leather or faux leather, although you can also find variations in other materials such as nylon or wool.
