The breed has been developed in the counties of Kent and Sussex in England since the 13th century. It is a long wool, true dual purpose breed producing well under extensive conditions. They are distinctly seasonal breeders. Due to their special claw structure, they are resistant to foot rot, and do not require hoof care. Easy lambing and progeny of 1.3 to 1.7 are typical of the breed. The fineness of fleece is 30-40 microns. Mature weights for ewes range from 50 to 70 kg, and ram weights vary from 80 to 100 kg.
