📏Helmet Size Chart
Measure your head circumference with a soft tape ~3 cm above your eyebrows, around the widest point at the back of your head. Match the cm value to your helmet’s size band on the product page.
Match Size
Compare your cm number to the size band on the product page (e.g. 54–58 cm). If you fall between bands, size up.
Adjustable Dial
Once on, turn the rear adjustment ring until snug. The chin strap should sit flat with no slack — fine-tune the V-yokes around your ears.
✓ How it should feel
Snug all the way around. Doesn’t move when you shake your head. Sits level — front rim about a finger above the eyebrows. No pressure points after 10 minutes.
✗ How it should NOT feel
Tilts forward or back. Slides side-to-side. Pinches the temples or forehead. Compresses ears. Has a gap between rim and forehead.
Size Chart Disclaimer. Helmet sizing varies between brands — this guide is general reference. Always check the specific cm range on the product page. We cannot be held responsible for incorrect size purchases — when in doubt, message us before ordering.
