Giro Atmos II Helmet

Legendary performance, style and comfort. The AtmosII 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.
