A COAT is a type of outerwear garment that is typically worn to protect the body from the elements. The term 'jacket or parka' refers to two specific types of coats: a jacket and a parka. A jacket is a hip- or waist-length garment for the upper body, usually with long sleeves and fastened in the front. A parka is a long, hooded COAT made of waterproof material, often lined with fur or synthetic material, and designed to keep the wearer warm in cold weather.
