Giro Ionos Road Cycling Helmet 2013

The Ionos is the most technologically advanced road cycling helmet Giro has ever created offering unparalleled style and ground breaking ventilation. 21 enormous Wind Tunnel vents and optimally placed internal exhaust channels maximise airflow across your head, ensuring that you stay cool on the hottest days and over the longest climbs. It has 15 percent better ventilation than the class leading Atmos.

A visible weave of composite called In-Mould Composite subframe runs throughout the helmet liner and around the vents. The use of composites in the sub-frame provides incredible structural support, impact dispersion and resistance to penetration.
