Bomber jackets are a type of jacket that was originally designed for pilots and later became a fashion trend. They are typically made of leather or nylon, and feature a zippered front, ribbed cuffs and waistband, and a low collar. They are a popular choice for both men and women, and are often worn as a stylish outer layer in cool weather. Some bomber jackets are designed to be weatherproof, with features such as water-resistant materials and insulation to keep the wearer warm and dry.
