Abstract
A face shield for a helmet comprises a body with an opening, an inner lens mounted in the body opening and a weather lens releasably mountable over the inner lens. The weather lens has a gasket around its perimeter which spaces the weather lens from the inner lens to form an insulating air gap between the inner lens and the weather lens. The weather lens is made of translucent material to selectively filter the light passing through the lens. The inner lens is recessed in the body so that the weather lens is generally flush with the outer surface of the body. Each side edge of the weather lens is provided with one of a hook and loop fastener and the inner lens has the complimentary fastener portion for mounting the weather lens to the inner lens.
