A greatcoat (also watchcoat) is a large, woollen overcoat designed for warmth and protection against wind and weather, and features a collar that can be turned up and cuffs that can be turned down to protect the face and the hands, while the short rain-cape at the shoulders protects from the wind and repels rain. In the 19th century, such a coat was part of a soldier's military uniform, to be worn while on watch (guard duty), hence the term watchcoat.
