The Atmos was the first helmet to utilize In-Mold Composite reinforcement, a breakthrough in helmet architecture that allowed 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 worldwide.
