A waist bag, or fanny pack, belt bag, moon bag, belly bag, or bumbag 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.
(1) Wear your fanny pack around your waist for a classic style. (2) Across your chest: for a more modern style look. (3) Across the Back: slide the pack around to your back.
