A golf bag having a shoulder strap assembly including a two strap system that can be converted to a single strap system is provided. In the two strap system, Strap A is fitted over one shoulder and Strap B is fitted over the other shoulder. To convert from a double strap configuration to a single strap configuration, Strap A is detached and slipped over the head area and coupled to Strap B. This results in a single strap comprising both Straps A and B. The combined Straps A and B are joined together by a suitable fastening means. For example, complementary male and female members that interlock with each other on the straps can be used. The shoulder strap assembly is durable, lightweight, easy to use, and comfortable. In another embodiment, a central hub connector having four open slots for retaining the shoulder straps is provided. The Straps A and B criss-cross each other in the hub connector. Strap A or B can be removed from the hub connector to convert the two-strap assembly to a single strap assembly.
