Abstract: A closure made of wind resistant material for motorcycle helmets. One embodiment of the closure has a front flap (20) which opens to allow the head to pass through the closure into the helmet. The front flap closes with hook and loop or other fasteners. The rear of the closure has an elastic panel (12) to allow stretching as the helmet passes over the head. An elasticized neck ribbing (14) closes around the wearer's neck. The closure attaches to the helmet by means of squeezing the outer (upper) edge of the closure between the helmet padding and helmet shell, as well as with hook and loop fasteners. In a second embodiment the closure has a continuous panel having front edge portions with one of hook and loop fasteners for removably securing the front edge portions to one another. A third embodiment has longitudinally extending straps for mounting the closure to the helmet.
