A bomber jacket is a type of jacket that was originally designed for pilots and flight crews. It features a streamlined design, with a slim fit and a snug waistband, as well as a zip-up front and a stand-up collar. The name "bomber" comes from the fact that these jackets were often worn by aircrew members during World War II, who would drop bombs on enemy targets. Today, bomber jackets are popular fashion items for both men and women, and come in a variety of colors and styles.
