Giro Aether Spherical Adult Road Cycling Helmet

COMPREHENSIVE PERFORMANCE AND PROTECTION: Engineered in Giro’s helmet test lab.
SPHERICAL TECHNOLOGY AND MIPS PROTECTION SYSTEM: Ball-and-Socket Design, powered by MIPS, redirects impact forces without compromising comfort, ventilation, weight or style. The market-leading protection system designed to address rotational motion, for an added measure of protection in certain impacts.
PROGRESSIVE LAYERING: Dual-density EPS foam liner designed to address high and low-speed impacts for more comprehensive energy management.
UNPARALLELED AIRFLOW: 21 Wind Tunnel vents and internal channeling allow air to flow through the helmet to enhance cooling power.
LIGHTWEIGHT AND DURABLE: In-moId construction eliminates excess weight and permanently fuses tough polycarbonate outer shell to the interior liner.
