Excellent performance, style and comfort. The Atmos™II utilizes the Thermoformed SL R oll Cage reinforcement, a breakthrough in helmet architecture that allows greater ventilation without compromising a helmet's integrity. The compact shape offers great style, and features the sure feel of a Roc Loc® 5 system that cradles your head comfortably and securely. This helmet is a favorite with road, XC and cyclocross riders worldwide not just because of its great wearing comfort in combination with high stability but also because of the Roc Loc® 5 system, optimal ventilation, minimum weight and the lightweight "Slimline" belt system.
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. It also features ergonomic arms to accommodate Giro eyewear, and a 15mm vertical bracket which you can adjust without removing your helmet.
In-Mold™ constructon 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.
Super Fit™ Engineering: A great helmet is so comfortable that once it's on, it virtually disappears. Giro's proprietary three-size Super Fit 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 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.
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.
