Patent attributes
Headwear such as a hat, cap, or visor with a headband and a brim extending outwardly therefrom includes a crescent shaped opening defined by an inner portion of the brim and an external leading edge of the headband. Beyond the opening the opaque brim extends away from the headband to an outward tip, and to lateral side edges. The opaque brim is attached at its lateral edges directly to the external leading edge of the headband. The crescent shaped opening allows more flow at a central area of the brim, yet it narrows toward lateral edges of the brim to ensure that sunlight toward the wearer's sides is adequately blocked from eye contact. This novel structure provides maximum shading of the wearer's face, yet directs considerable airflow from beneath and above the brim through the opening to cool the wearer's eccrine glands along the forehead.
