The Giro Atmos Bicycling Helmet continues to set the standard for high performance, matchless style, and comfortable fit. Its low profile silhouette, 26 Wind Tunnel vents, and benchmark in-mold Roll Cage make it a top choice for road, ?cross, and XC riders alike.

• Highly adjustable and ultralight Roc Loc® 5 retention system ensures a perfectly dialed fit
• 26 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 light, cool and tough helmet
• Roll Cage™ reinforcement provides an extra measure of strength and integrity that you'll never notice (unless you need it)
• The Giro Atmos helmet features an integrated, low-profile silhouette that helps it weigh in at a featherweight 269g
