Duffel bag

Historically a duffel bag had a top closure using a drawstring.

[2] Later bags had a webbing hand grip, along with a shoulder strap with clip that closed the bag by nesting grommets from around the rim of bag, over padlockable eye loop, later an independent pair of ruck sack straps were used.

Generally a duffel bag is used by non-commissioned personnel in the military, and for travel, sports and recreation by civilians, especially schoolchildren, who may use them to carry their physical education or football kits.

A duffel's open structure and lack of rigidity make it adaptable to carrying sports gear and similar bulky objects.

[9] According to the Oxford English Dictionary, the word dates back to 1649, used to describe ‘a coarse woollen cloth having a thick nap or frieze’.
