Abstract: This invention provides a flag (1), consisting of a flexible membrane (2), a shaft (3) and a distending mechanism comprising resilient rods (4.1) and (4.2). The shaft (3) is hollow and forms a sleeve about a flag staff (7). The flexible membrane (2) has a leading end (5) and a trailing end (6). The leading end (5) is removably attached to the shaft or sleeve (3). Each rod (4.1) and (4.2) has a fixing end and a free end. The fixing ends are frictionally fixed to the sleeve (3) by a collar (8) located on the sleeve, and the free ends are retained in pockets (6.1) and (6.2) provided in the trailing end (6). In use, the rods (4.1) and (4.2) exerts a pressure from within the membrane (2), resulting in the distended state of the flag (1) under all weather conditions.
