Key Features

Super Fit Engineering™

The right helmet should be so comfortable that is virtually disappears once its strapped to your head. Giro’s proprietary three-size Super Fit System is based on “human scale factors” data and nearly 20 years of helmet crafting expertise. The result is a line of helmets that fit 98% of the worlds population, yet look and fit like they were made just for you.

Wind Tunnel Ventilation & Internal Channels

Giro’s exclusive Wind Tunnel™ ventilation system is utilized in the design of each helmet. This combines 17 active vents with carefully crafted internal exhaust channels which bring cool, fresh air over and around the riders head, while forcing heat and stale air out. Just another way Giro helps keep your ride cool and comfortable.

P.O.V. Visor

Anchored by a patented internal clutch mechanism, Point of View Visors allow 15 degrees of vertical adjustment and prevent the visor from rattling and coming loose over rough terrain. As lighting conditions shift during your ride, you are able to simply adjust the visor as needed.

In-Mold Technology

In-mold construction fuses the helmet’s outer shell with the impact-absorbing EPS liner. The two materials are fused together, and one is reinforced by the other. This ‘exoskeleton’ enables Giro to engineer helmets that are lighter and more durable well producing supreme ventilation.

Internal Channels

By definition, a channel is; a route through which anything passes or progresses. In the case of Giro helmets, we utilize channels on the inner portion of the helmet to move air. These internal channels are carefully crafted and are one of the keys to a well ventilated helmet. When combined with our external vents, they help move hot, stale air across the riders head and force it out the back of the helmet. This is a proprietary Giro technology that we call WindTunnel Ventilation.
