    • A face mask which repels rain and airborne debris comprises two spinning, transparent screens 1 powered by electric motors (6, fig. 2). The motors drive the outer rings of bearings (7, fig. 2) upon which the screens are mounted. A warm air flow generated by the electric motors may be ducted to an inner surface of the screens to prevent condensation (see fig. 3). A battery (not shown) for powering the motors may be remotely located and connected via a wiring harness (not shown). The mask may be integral with a helmet visor, such as a motorcycle helmet, or may be attached as a supplement to a helmet visor. When attached to a visor, the mask may have a seal (14, fig. 3) for preventing ingress of water between the visor and the mask, and may attach using a securing strap 4, 5 having hinge means (not shown) allowing the mask to be raised along with the helmet visor. It is intended that centrifugal forces generated by the spinning action of the screens causes water and airborne debris to be thrown towards the edge of the screens, thus clearing the field of view of a wearer.
