 The name derives from French meaning "over the coat", a long, loose, often sleeveless coat reaching down to the feet.From about the 12th century, knights wore long, flowing surcoats, frequently emblazoned with their personal arms, over their armor.These usually extended to about mid-calf, had slits in the bottom front and back, allowing the wearer to ride comfortably, and were either sleeved or sleeveless.
