A leather jacket is a jacket-length coat that is usually worn on top of other apparel or item of clothing, and made from the tanned hide of various animals. The leather material is typically dyed black, or various shades of brown, but a wide range of colors is possible. Leather jackets can be designed for many purposes, and specific styles have been associated with subcultures such as greasers, motorcyclists and bikers, mobsters, military aviators (especially during and directly after World War II) and music subcultures (punks, goths, metalheads, rivetheads), who have worn the garment for protective or fashionable reasons, and occasionally to create a potentially intimidating appearance.
Most modern leather jackets are produced in Pakistan, India, Canada, Mexico and the United States, using hides left over from the meat industry. Fabrics simulating leather such as polyurethane or PVC are used as alternatives to authentic animal hide leather depending on the needs of the wearer such as those pursuing vegan lifestyles or for economic reasons as synthetic fibers tend to be less costly than authentic leather.
