Sleek And Stylish


Now upgraded to RocLoc 5, the Ionos is the most technologically advanced road cycling helmet Giro has ever created, offering unparalleled style and ground breaking ventilation. It's 21 enormous Wind Tunnel vents and optimally placed internal exhaust channels maximize air flow across your head, ensuring that you stay cool on the hottest days and over the longest climbs. As a result, the Giro Ionos has 15 percent better ventilation than the class leading Atmos.

A visible weave of composite, the 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. As a result, the Ionos incorporates huge vents without compromising protective capability. Giro's X-Static fabric pads are woven with pure silver fibres and kill 100 percent of bacteria, inhibiting growth of odour-causing bacteria and funghi within 4 hours of finishing your ride.
