The Giro Atmos II Road Bike Helmet provides legendary performance, style and stay-cool comfort. The Atmosâ¢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 matchless style, and features the sure feel of a Roc Loc Â® 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.
In-Mold Construction 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.
Roc Loc 5 allows you to easily custom tune the fit tension and the fore-aft tilt of the helmet in seconds using a single hand.
Roll Cage is a light-yet-tough web of reinforcement invisibly molded inside a helmet's EPS foam liner. It helps the helmet to hold together under impact, and provides an extra measure of strength and integrity that you'll never notice...unless you need it.
Super Fit sizing system is based on âhuman scale factors data and over 25 years of handcrafting helmets.
