Golf bag with circumferential stay

A golf bag 10 has a tubular body 16 with partially collapsible side and a diametrically opposite rigid side, a circumferential stay 56 mounted to the collapsible side, preferably near the bottom to prevent collapse of the bag. The bag may have an automatically extensible stand mounted on the collapsible side of the bag and the rigid side may be formed by a longitudinally extending spine 28. The stay may extend through at least 270 degrees, be held in pocket (58, Fig. 1) on the outside of the bag or may comprise a flexible, arcuate rod which lies at an angle to the to the axis defined by the spine.
