A visor configured for engagement to a riding helmet for horseback riders in an as-used position. The visor has an extra long frontal bill which extends around the helmet to side portions. The bill protects the eyes and most of the rider's face from sun and the sides protect the ears and side of the face. An elastic band provides a biased engagement to a helmet and optional vent apertures and retainment clips are employable to hold the device to a helmet more securely in high wind.
