  • Patent number: 4722099
    Abstract: Conductive and evaporative cooling are provided in a natural or artificial leather motorcycle garment by including mesh vents at locations which require little protection, such as adjacent the underarms extending from chest to back, inside the elbows, and at the neck. Scoops which open in response to a predetermined air flow velocity and constrict in response to higher velocities are also provided. The scoops are positioned at the top of the shoulders, at the outside of the knees, and at the lower outer thighs so that a positive flow of air is established throughout the garment at speeds over 5 miles an hour for removal of heat from the body at a comfortable rate. The back is allowed to billow slightly to provide a air flow conduit across the back and prevent contact heating from solar radiant effects. A fire proof gabardine panel is provided in the crotch area and on the inside of the knees where evaporative cooling is required yet maximum protection is needed.
