How to Measure: Wrap a soft measuring tape around the widest part of the head, just above the eyebrows and ears. Keep the tape level and comfortably snug.
Fit Note: A motocross helmet should fit securely around the crown and cheeks without painful pressure points or excessive movement. Do not intentionally size up for a loose fit.
The interactive size finder uses head circumference in inches to recommend the appropriate helmet size.
