Availability: Out of stock



The Giro Atmos bike helmet continues to set the standard for high performance, matchless style, and comfortable fit. The Atmos offers such features as a proprietary in-mold design that provides the strength to support 26 cooling vents, a benchmark in-mold roll cage, and a low-profile silhouette. The vents are particularly comforting, as they work in tandem with an intricate network of internal channels to create a cooling system dubbed Wind Channel ventilation. The upshot? The Atmos is one of the coolest helmets around, making it a top choice for road, 'cross, and XC riders alike.
