How to measure
Measure the circumference of your head one inch above the eyebrows and across the largest portion of the back of the head, then find the matching range. The crown should apply snug, even pressure and cheek pads should be snug (they break in with use). If the helmet moves on your head it is too loose; if it causes pain it is too small. If between sizes, size down.
