Abstract: A visor for automotive use including a plurality of air directing channels for reducing the aerodynamic drag of the visor. The visor is formed from a single sheet of material and the channels are formed by flat bottomed depressions beginning near the front edge of the visor and becoming progressively deeper to a point near the back edge of the visor. From this point, the bottom of the depression abruptly rises back to the visor surface. The depressions have a maximum width near the front edge and taper to half this width near the back edge of the visor. The channels direct air from under the visor through openings formed between the visor and the vehicle and exhaust the air with essentially laminar flow.
