Giro Ionos Road Helmet
Ionos is the most technologically advanced road cycling helmet Giro has ever created. Their revolutionary in-mold composite sub-frame (I.C.S.) provides the strength to support 21 of the largest vents ever carved into a helmet. These massive vents, coupled with an intricate network of internal exhaust ports, create a cooling system we call Wind Tunnel ventilation. Ionos keeps riders like, Grand Tour Triple Crown Champion, Alberto Contador cool and comfortable all season long.
