duffeln.

duffelduffel: [17] Duffel is actually a sort of heavy woollen material, and like so many names of fabrics, it comes from the place where it was originally made or exported from – in this case Duffel, a town in Belgium, near Antwerp. However, the term duffel coat (which dates back to the late 17th century) has in modern times become associated with a particular design of coat (with a hood and toggles) as much as with the material it is made from. Duffel bag [20], a term of American origin, was to begin with a bag for ‘personal belongings and equipment’, or duffel, as it is called in American English (the application seems to have started with ‘spare clothes made of duffel’).duffelsee duffle.
