The broad pad is molded onto the inside surface of the tube. It is designed to gently warm the air in the area in fornt of the mirror, warmer air can hold more moisture and thus slow or prevent the formation of dew, the moving air caused by the rear fans also helps here too and produces a laminar air flow .
