GIRO Ionos Bike Helmet No Shipping Charge for a Limited Time! The Giro Ionos bicycle helmet is the most ventilated and technologically advanced road cycling helmet Giro has ever created. Giro utilizes their proprietary in-mold composite sub-frame (I.C.S.) which provides the strength to support 21 of the largest vents ever carved into a bike helmet. These massive vents are combined with an intricate network of internal channels which create a cooling system Giro calls Wind Tunnel ventilation. The difference is remarkable and after one ride, we are sure you will agree. With the Ionos, Giro created the coolest and best ventilated helmet available. This is the reason that Grand Tour champions like Lance Armstrong and Alberto Contador choose Ionos to stay cool on the hottest days.
