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 animal skins. 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 and music subcultures, who have worn the garment for protective or fashionable reasons, and occasionally to create a potentially intimidating appearance.

A flight jacket is a casual jacket that was originally created for pilots and eventually became part of popular culture and apparel. It has evolved into various styles and silhouettes, including the letterman jacket and the fashionable bomber jacket that is known today.
