Giro Atmos II Helmet
Legendary performance, style and comfort. The Atmos II utilizes our 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 matchless style, and features the sure feel of a Roc Loc 5 system that cradles your head comfortably and securely. It’s no wonder this helmet continues to be a favorite with road, XC and cyclocross riders worldwide.
