Key Features

Integrated Mips® Brain Protection System – Designed to reduce rotational forces during certain impacts, Giro’s Integrated Mips® technology combines a slip-plane system with the helmet’s adjustable fit system for enhanced comfort, fit, and protection—all while meeting and exceeding top safety standards.

Hard Shell Construction – Durable and budget-friendly, this construction features a rugged outer shell fused to an EPS foam liner for reliable impact protection.

Seamless Compatibility – Engineered to work flawlessly with Giro goggles, delivering a snug, gap-free fit and consistent performance on the mountain.

Stack Vent Technology – Strategically placed to align with the top center vent of your goggles, Stack Vent helps reduce fogging by allowing warm, moist air to escape efficiently.

Thermostat Control™ – Instantly fine-tune airflow with a low-profile external control—no other venting system is faster, easier, or more effective at maintaining all-day comfort.

Vertical Tuning – Allows you to adjust the helmet’s position for a personalized fit that eliminates pressure points and goggle gaps.

In Form Fit System – Quickly dial in your ideal fit—even with gloves on—thanks to the ergonomic dial offering up to 6cm of adjustment and increased stability.
