Sizing Chart

The following is a sizing chart.  This is to be used as a reference, but to properly fit a helmet it is important that you try it on.  If you are not able to try it on prior to purchasing product, it is important that you do so upon receiving the helmet.  Dealers are not able to exchange used helmets.
