The Roc Loc® 5
is an improved retention system with a micro-adjusting dial which is easy to use: a simple twist of the dial opens or tightens the retention system of the helmet.

fuses a tough polycarbonate outer shell with the helmet's impact-absorbing foam liner. The fusion process allows for better ventilation systems, making in-mold helmets lighter and cooler than traditional helmets.
A great helmet is so comfortable that once it's on, it virtually disappears. Giro's proprietary three-size Super Fit™ Engineering
system is based on "human scale factors" data and over 20 years of crafting helmets for the best bike riders in the world. The result is pure Skull Hugging Luxury™, a helmet that fits 98% of the world's population, yet looks (and fits) like it was custom made just for you.
The Wind Tunnel™
elaborate design combines active vents in the helmet's shell with exhaust channels inside the helmet that thrust fresh, cool air over and around the rider's head while forcing heat and stale air out.
contains a fiber made with layers of pure silver that is permanently woven into the fabric. Silver has natural anti-microbial performance that helps to reduce odor and regulate heat, so your helmet stays fresh and comfortable, naturally. The Pads are machinewashable.
The Thermoformed SL Roll Cage™
is an ultra light polycarbonate skeleton fused into a helmet's impact-absorbing foam liner. Visible on the bridges between vents, this layer of armor acts like a second shell, enhancing structural support, impact dispersion and penetration resistance while allowing us to carve the biggest vents possible without compromising the helmet's strength of integrity.
