Breathe easy with 25 vents which use Giro’s own Wind Tunnel Ventilation System to force cool air through the helmet and hot air out of the helmet. The Integrated MIPS® Technology is a highlight of this model, protecting you against rotational forces and offering excellent protection in combination with the full-wrap in mould polycarbonate shell with EPS liner. The ROC LOC Fit Adjustment System ensures that you can adjust the fit to suit your own personal needs and the visor P.O.V feature lets you adjust the visor to suit three riding positions. The Giro Radix MIPS Helmet gives you the ideal balance of safety, comfort and ventilation so that you can get the most out of your ride.
