Helmet Sizing Guide

First determine head size by measuring the circumference of the top of the head appx. 1″ above the eyebrows. Use that to determine the helmet size using the chart below.

To properly adjust the helmet open to its largest adjustment and place on head so the rim is approx. one finger width (1/2″) above the eyebrow. Then begin to downsize the helmet until helmet is snug.

The face mask should fit so that the chin fits snug into the chin cup with the mouth closed. The chin cup should not hang down lower than the chin or ride up into the mouth area.
