Waistpack

A fanny pack (American English) or bum bag (British English) is a small fabric pouch usually secured with a zipper and worn by use of a strap around the hips or waist. The 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 the slang terms in each country respectively, although they may also be worn with the pouch at the front.

Bags attached to belts have been in use since antiquity in many cultures. One origin was the Native American buffalo pouch which was used instead of sewing pockets into clothing. Buffalo pouches may also be worn on the wrist or carried on the front of the chest via a neck strap or lanyard. The European medieval belt-pouch is another antecedent which was superseded as clothing came to have pockets. The Scottish sporran is a similar belted pouch that survived because of the impracticality of pockets in a kilt.

The modern version made from synthetic materials came into use in the 1980s and they were especially in vogue in the 1990s, but are now often considered old-fashioned. Their use was satirised by the American humorist Weird Al Yankovic in his song White & Nerdy.

In 2012, calling them "belted satchels" or "hands-free bags", several designer labels sought to bring the accessory back by offering stylish and expensive designs selling for as much as $1995.

Fanny packs designed for concealed carry of a weapon are available.

In other cultures they are known as belly bags (in Germany) and banana bags (in France). Variations include the wristpack, which is essentially a fanny pack for the wrist.

In 2009, the first wearable technology fanny pack was introduced in the United States in the form of a portable speaker bag aptly named, "JammyPack". The Southern California startup incorporated speakers into the front face of the fanny pack and utilized trendy phone s enabling the individual to share their music of choice. Later, in 2013 JammyPack introduced Bluetooth technology into their unique fanny pack creation.
