Sizing
Since our designs are proprietary, our helmets DO NOT fit like the cheaper universal helmets. Please measure your head before ordering. Just in case, we always call you to confirm the correct size and see if we can answer any other sizing questions before shipment.
The Best Fit is an Initially Snug Fit. Our helmets mold to your head after a short period of usage.
