From the ProTour to local group rides, Giro's Atmos is a favorite of roadies everywhere. It's crafted with a whopping 26 vents and Wind Tunnel technology to pull cool air in and blow hot air out, a vital function for racing's extreme efforts. In addition to being light and airy, the Atmos is super durable thanks to Giro's Roll Cage and carbon-reinforcement technologies that protect your head when you need it most. Plus, it boasts Giro's Roc Loc 5 retention system for a perfect fit.
