HEAD CIRCUMFERENCE — Wrap a measuring tape around the head, keeping the tape level from front to back. Note the measurement and reference the Size Guide.
Note — A Giro helmet should fit with a little room when the fit system is loose, and sit low enough to protect your forehead without hindering your vision. From there, you can adjust the fit so it is more secure and comfortable.
