Abstract: A golf bag of variable configuration includes a tubular pillar to which are hinged two compartments each having a triangular cross-section. The compartments extend parallel to the tubular pillar and are open at one end. The two compartments are movable angularly between an open position in which they are spaced from each other and define with the tubular pillar a longitudinal outwardly-open V-shaped seat and a closed position in which they are side by side. An auxiliary container having a shape substantially complementary to that of the longitudinal seat can be fitted removably into the seat when the two compartments are in the open condition.
