Giro Atmos Bike Helmet

Superior technology and Tour de France-proven performance are why so many elite riders count on the Atmos. Luxurious Roc Loc 4 ensures a perfectly dialed fit. Twenty-six Wind Tunnel™ vents channel airflow for maximum cooling. In-mold carbon reinforcement fuses a tough outer microshell to the helmet's liner to create a lighter, cooler and tougher helmet. Roll Cage™ reinforcement provides an extra measure of strength and integrity that you'll never notice (unless you need it). Interior strap anchors provide a more secure fit.
