A duffel bag (duffle bag, kit bag or gym bag) is a large cylindrical bag made of cloth (or other fabric) with a drawstring closure at the top.
The name comes from Duffel, a town in Belgium where the thick cloth used to make the bag originated. More recently, a duffel bag typically refers to the specific style of bag, though the phrase may also be used to refer to any large generic holdall or a bag made of thick fabric.
