Giro Ratio™ MIPS Helmet
The Ratio™ MIPS delivers premium features without the premium price. Designed with a clean, streamlined silhouette, this helmet packs in high-end tech to keep you comfortable and protected on the mountain. Inside, you’ll find the customizable In Form Fit System for a precise fit, Thermostat Control™ adjustable venting for easy airflow regulation, and audio compatibility with Outdoor Tech® systems for seamless sound integration.

For added peace of mind, the Ratio is available with MIPS® (Multi-Directional Impact Protection System), which helps reduce rotational forces during certain impacts by redirecting energy away from the brain.

High performance, smart protection, and all-day comfort—the Ratio™ MIPS is proof that great gear doesn't have to break the bank.
