COMPREHENSIVE PERFORMANCE AND PROTECTION: Engineered in Giro’s helmet test lab. SPHERICAL TECHNOLOGY: Ball-and-Socket Design, powered by MIPS, redirects impact forces without compromising comfort, ventilation, weight or style. MIPS PROTECTION SYSTEM: 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. EXCEPTIONAL AIRFLOW, LIGHTWEIGHT, AND DURABLE: 15 Wind Tunnel vents with internal channeling allow air to flow through the helmet to enhance cooling power. construction eliminates excess weight and permanently fuses tough polycarbonate outer shell to the interior liner.
