Abstract: A bag strap functions as a one-shoulder carrier or a two-shoulder carrier at any time according to the desire of the golfer. Reconfiguring the strap to convert from a one-shoulder type to a two-shoulder type, or visa versa, is easy and quick and can be accomplished even during a round of golf. The strap comprises two nested layers. When the two layers are secured together by a VELCRO hook and loop fastener and secured to upper and lower back rings by hooks, the strap functions as a one-shoulder strap. The nested configuration permits a comfortable, padded one-shoulder strap that is still reasonably thin and not unduly heavy and thick. Alternatively, strap layers may be separated from each other and the lower ring used as a slip through ring for an elongated belt secured by a slide-release buckle for encircling the golfer. Each layer is worn over a respective shoulder with the bag carried diagonally across the golfer's back.
