The invention relates to a method for producing blow-moulded sun visors comprising outer surfaces with a preferred embodiment. The outer surface of the sun visor varies in colour, surface structure and roughness. An economically-produced sun visor can thus be obtained to match the interior fittings of any motor vehicle. The structure and roughness of the outer surface of the sun visor are complementary to the inner surfaces ( 4 ) of the blow mould ( 1, 1 '). The colour of the outer surfaces of the sun visor is also adjusted according to the coloration of the polypropylene used ( 2 ). Said coloration is obtained from organic and inorganic pigments. The invention also relates to a zip-up material cover for sun visors, which can easily be taken off and changed as required. The zip is almost completely covered by the hem and therefore cannot be seen by the passengers in the vehicle.
