Fanny pack

A waist bag, fanny pack, belt bag, moon bag, belly bag (American English), or bumbag (British English) is a small fabric pouch worn like a belt around the waist by use of a strap above the hips that is secured usually with some sort of buckle. The straps sometimes have tri-glide slides, making them adjustable in order to fit properly. It can be considered as a purse worn around the waist.

Although traditionally the bag is worn with the pouch at the front, the separate American and British names derive from the fact that they are often worn with the pouch above the buttocks, for which "fanny" and "bum" are respective slang terms in each country. In France, they are known as banana bags, in Spain and Poland as kidney bags, in Italy as the marsupio, from marsupium. In Costa Rica, they are called a skippy or canguru.

The modern bags resemble those used from antiquity in some cultures and have gone in and out of fashion from the second half of the 20th century. From the mid-2010s the bag is often worn crossbody.
