HJC C10 Adult Helmet Size Chart

How to Measure: Wrap a soft measuring tape around the widest part of the head, approximately one inch above the eyebrows and around the largest portion at the back of the head. Keep the tape level and snug without pulling it tight.

Fit Note: A motorcycle helmet should fit securely and evenly around the head without painful pressure points. It should not move excessively when the rider turns or shakes their head.

The interactive size finder uses head circumference as the primary measurement. For helmets, proper secure fit should take priority over a looser fit preference.
