How to Choose Your Helmet Size
HELMET SIZING IS NOT STANDARD. PLEASE USE OUR HELMET SIZE CHART BEFORE PURCHASING OUR HELMETS.
Our helmet size chart covers all of our helmets including our adult and youth motocross helmet, full face helmet, and modular helmets.
Sizing Chart: Size is determined by your head's circumference (see our helmet size chart below in inches):
Step 1 - Use a paper tape measure or a piece of string.
Step 2 - Wrap the tape measure or string around your head at its largest circumference - usually just above your eyebrows in front, over your ears and around in back - then mark.
Step 3 - Measure with ruler (if using string). When in doubt, order the next size larger.
NOTE: Youth helmets, including our youth motocross helmet, are not recommended for children younger than 5 years old.
