A surcoat is a loose-fitting garment worn over armor, primarily during the Middle Ages. It was often made of fabric and featured a design or emblem that represented the wearer, such as a knight's heraldic symbol. Surcoats helped to identify knights in battle and added a layer of protection against the elements. In addition to its practical use, the surcoat also served a decorative purpose. Many knights wore colorful and intricately designed surcoats to showcase their status and wealth. This garment became a significant part of medieval fashion, reflecting the culture and values of the time.
