This elegant take on the classic fanny pack functions as a cross-body, handbag and waist-pack. The Bum Bag features a top carry handle and a quilted and structured back wall to hold its shape and sit comfortably against your body. The Bum Bag is sized to fit an 18 oz. water bottle, keys, wallet, phone and snacks. In addition to a roomy main compartment, the bum bag sports a hidden large back zipper section and a small front slip pocket. This piece works well as a stylish sling across the chest as well as in traditional fanny pack/waist pack mode.
