The Ratio™ Mips® helmet has the perfect ratio of everything you need to accompany you on the mountain, from its Thermostat Control Adjustable Venting to its Mips® technology to its laid-back style.
Beneath the sleek silhouette, you'll find the adjustability of an In Form fit system, Thermostat Control adjustable venting and compatibility with aftermarket audio systems by Outdoor Tech. The Ratio is also available with Mips® - which can offer more protection in certain impacts by redirecting impact energy.
- INTEGRATED MIPS® BRAIN PROTECTION SYSTEM — All Giro helmets are designed to reduce as much energy as possible while meeting and exceeding stringent safety standards. The goal of Giro's Integrated Mips®-equipped helmets is to reduce rotational forces while enhancing fit and comfort by combining the Mips slip plane with the helmet's adjustable fit system. Giro believes that helmets equipped with this technology can reduce the amount of rotational force that may be transferred to rider's brain in certain impacts. Learn more about Mips in the video above.
- HARD SHELL CONSTRUCTION — Hard Shell Construction produces great helmets at a great price. A rugged outer shell is molded and then attached to the EPS foam liner.
- SEAMLESS COMPATIBILITY — For optimal performance of both helmets and goggles, Giro products are designed to work together, ensuring a seamless interface between helmet and goggle for an exceptional fit and dependable, worry-free function.
- STACK VENT TECHNOLOGY — Our Stack Vent was developed based on research showing the majority of warm air that can cause fogging comes from the goggle's center top vent. Aligning the Stack Vent in the helmet with the center vent of the goggle helps keep it clear and fog-free.
- THERMOSTAT CONTROL — Thermostat Control Adjustable Venting allows you to custom-tune airflow instantly with a simple, low profile control button on the outside of the helmet. No other system is faster or easier to adjust, and nothing is more effective at keeping you comfortable.
- VERTICAL TUNING — Accommodates different goggles and head shapes for a custom fit free of gaper gap
- IN FORM FIT SYSTEM — The In Form Fit System makes it easy to dial in a custom fit in seconds - even with gloves on. An ergo-friendly dial at the base of the helmet provides up to 6cm of adjustment and enhanced stability.

Snow Helmet Size Guide
How to measure your size – Wrap a measuring tape around your head, keeping the tape level from front to back. Note the measurement and reference the Size Guide. Note: Make sure the helmet fits with a little room when the fit system is loose, and sits low enough to protect your forehead without hindering your vision. Once you’ve got the right size, you can adjust the fit.
