Abstract: A combination helmet and rear view mirror to enable a wearer to observe objects and events occurring behind him without having to turn his head around to look backwards. In a preferred embodiment, the helmet is of the type that is commonly used by one playing baseball or softball. A mirror is affixed to the helmet at the underside of the brim thereof so as to lie above the eyes and in the line of sight of the wearer. In this manner, the wearer (i.e., a batter) will be better able to see reflections in the mirror corresponding to the movements of the catcher behind home plate so that the batter will quickly and easily gain an early indication of the catcher's target for the pitcher and the intended location of the next pitch to be thrown, whereby to increase the batter's chances for hitting the ball and successfully reaching base.
