Ionos is the most ventilated and technologically advanced road cycling helmet Giro has ever created. Giro’s proprietary 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 channels–create a cooling system we call Wind Tunnel ventilation. The difference is remarkable and after one ride you’ll agree: the Ionos is the coolest, 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.

Giro helmets are developed utilizing our proprietary Wind Tunnel ventilation system, which combines active vents with internal exhaust channels that thrust cool, fresh air over and around the riders head-while forcing heat and stale air out. This significant increase in air channeling makes a difference that riders will immediately feel and appreciate.

After more than two-years of development, Giro introduces Roc Loc 5. This groundbreaking fit system provides an entirely unique user experience with an unmatched level of comfort, stability, adjustability and weight savings. With Roc Loc 5, you can easily dial-in both fit tension and adjust vertical position with a single hand. Just twist the dial for a tighter feel on rough terrain, then back it off a notch and relax across the flats or a warm climb. Even with these remarkable features, Roc Loc 5 is still nearly 40-percent lighter than its popular predecessor, Roc Loc 4.
