Duffel (Dutch pronunciation: [ˈdʏfəl] ⓘ) is a municipality in the Belgian province of Antwerp.

The area is the eponym of a coarse woolen cloth, manufactured in this area from the 11th century, mainly used to make blankets, outdoor (army) coats, and tote bags.

Duffel became a household name during and after World War II in the meaning of a coat designed with toggle-and-loop fastening and roomy hood.

[2] The etymology of Duffel is from "dubro" and "locus", from the Gaulish dubrum, dubron – "water".

[4] In the Middle Ages, an important part of the region's industry was the manufacturing of Flemish laken (a broadcloth), while the cloth produced in Duffel was a thicker variation.
