Or duffel. A heavy woollen fabric, named after the Belgian town of Duffel, where the thick and robust outdoor fabric was first made in the 17thC.
Duffle coats for winter weather are junior school classics. They are easy to put on and off, have a pull over hood and the distinctive toggles that fasten over a wide, windproof flap.
The fabric and the classic toggle fastening are both useful interior furnishings materials and ideas –
