A riding helmet comprises an outer shell 3, an impact absorbing lining 5 inside the outer shell and a strap 7 for releasably securing the riding helmet in position on a user's head. The helmet has a damage indicator device 9 and a damage indicator device activation means 11. The damage indicator device activation means is responsive to an impact to the riding helmet and activates the damage indicator device upon the riding helmet being subjected to an impact of at least a given magnitude sufficient to cause damage to the riding helmet. Preferably, the damage indicator device is mounted on the exterior of the riding helmet. The indicator may be a dye, a chemi-luminescent liquid, a light or an audible alarm.
