Product Description Amazon.com Product Description The Ionos is the most technologically advanced road cycling helmet Giro has ever created. The Ionos is built around a proprietary in-mold composite sub-frame (ICS) that provides the strength to support 21 of the largest vents ever carved into a bike helmet. These massive vents, coupled with an intricate network of internal channels, creates a cooling system dubbed Wind Tunnel ventilation, making Ionos the coolest, best-ventilated helmet on the market. The helmet is perfect for keeping Grand Tour champions like Lance Armstrong and Alberto Contador cool on the hottest days and over the most tortuous Alpine climbs.

The helmet's Wind Tunnel ventilation thrusts cool, fresh air over and around the rider's head. Ionos Technologies
The Ionos helmet employs some of the most advanced technologies that Giro has ever used in a bike helmet. The Ionos' in-mold construction, for example, fuses the helmet's outer shell with the impact-absorbing EPS liner. Not only does this reinforce both layers, but the "exoskeleton" also allows Giro to engineer helmets that are lighter, more durable, and better ventilated. This culminates in the helmet's proprietary Wind Tunnel ventilation system, which combines active vents with internal exhaust channels that thrust cool, fresh air over and around the rider's head while forcing heat and stale air out. By definition, a channel is a route through which anything passes or progresses. In the case of Giro helmets, the internal channels are carefully crafted and are one of the keys to a well-ventilated helmet. This significant increase in air channeling makes a difference that riders will feel immediately.
The secret behind the vent technology is the in-mold composite subframe, which lets Giro offer huge vents without compromising protection. The Ionos features a visible weave of carbon reinforcement that runs through the helmet's liner and around the vents. By using these advanced materials, the sub-frame can be tuned to provide incredible structural support, impact dispersion, and resistance to penetration.
Padding and Fit
The Ionos offers X-Static helmet padding, which is entwined with an environmentally friendly silver-coated fabric called Silver Fiber. Found exclusively in Ionos helmets, the fabric provides anti-microbial and thermodynamic benefits, so in addition to keeping you cooler in the summer and warmer in the winter, your helmet will stay fresh all year round. Finally, the Ionos helmet is engineered using Super Fit technology, making it so comfortable that it virtually disappears when you put it on. The proprietary three-size Super Fit system is based on "human scale factors" data and nearly 20 years of crafting helmets for the best riders in the world. The result is a helmet that fits 98 percent of the world's population, yet looks and feels like it was made just for you.
