From the top of the podium of the Tour de France, straight to your head comes Giro's Ionos. Built to the exacting demands of ProTour riders, the Ionos offers premium cooling, chic style and maximum protection. 21 massive Wind Tunnel vents keep your head airy and dry, while the In-mold Composite Sub Frame provides massive amounts of protection when you need it most. Plus, the Ionos uses Giro's top-notch Roc Loc 4 system for a supremely comfortable and secure fit. And, this sweet lid is available in the colors of some of your favorite professional cycling teams.

How can the Ionos be so light and cool, and still meet the toughest safety standards? The secret is the use of a tough composite (the sections that look like white carbon in the photo). Giro calls this the In-mold Composite Sub Frame. It runs throughout the helmet liner and around the vents for incredible structural support, impact dispersion and resistance to penetration. It's also how the Ionos can have great big vents for amazing cooling and offer awesome protection, too.
