Wrap a measuring tape around your head, keeping the tape level from front to back. Note the measurement and reference the Size Guide. Note: Make sure the helmet fits with a little room when the fit system is loose, and sits low enough to protect your forehead without hindering your vision. Once you’ve got the right size, you can adjust the fit.
