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.
I use this helmet for both road and trail riding. Really keeps your noggin cool and fits oval shaped heads great! Worth the price tag for the comfort and cooling it provides!
