Ionos is the most technologically advanced road cycling helmet Giro has ever created. Or anyone else. Our revolutionary in-mold composite sub-frame (I.C.S.(tm)) 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(tm) ventilation, making Ionos the coolest, best-ventilated helmet anywhere…perfect for keeping riders like 2007 Tour de France champion Alberto Contador comfortable, even on the hottest days and over the most tortuous Alpine climbs.S 20"-21.75" / 51-55cm
