## Long description

GIRO Ratio Mips is an open-face helmet designed for urban commuting and recreational riding. It pairs a hard-shell construction with Mips rotational protection and an In Form fit system to provide a secure, adjustable fit. Stack Vent ventilation and Thermostat Control adjustable venting help manage airflow, while a matt finish gives the helmet a low‑gloss appearance.
Advantages
The helmet combines a durable two-piece hard shell with a lower polycarbonate wrap fused to the liner for long-lasting protection without excess weight. Integrated Mips aims to reduce rotational forces in certain impacts while the In Form Fit System provides up to 6 cm of quick, tool-free adjustment for a stable, tailored fit. Stack Vent alignment with goggle vents and Thermostat Control adjustable venting offer effective airflow management.
Suitable for
Urban commuting and city riding
Leisure and recreational cycling
Riders who want durable hard-shell protection with adjustable fit
When it may not be suitable
This open-face helmet is not optimized for full-face protection required in high-speed downhill or aggressive mountain-bike disciplines. Riders seeking the maximum facial and chin protection should consider a full-face helmet designed specifically for those disciplines. Additionally, if extremely lightweight shell construction is the priority, some ultralight in-mold helmets may offer lower weight.
Key specifications
Construction: two-piece hard shell with polycarbonate lower wrap
Protection system: integrated Mips rotational protection layer
Fit system: In Form Fit System with up to 6 cm adjustment
Ventilation: Stack Vent alignment plus Thermostat Control adjustable venting
Finish: matt low‑gloss surface
Compatibility: seamless fit with Giro goggles; compatible with aftermarket audio systems
How to use
Place the helmet on your head and use the In Form dial at the base to tighten or loosen the fit until it feels secure and stable. Adjust the Thermostat Control to regulate airflow depending on temperature and exertion level. Ensure straps are fastened and snug under the chin, and verify the helmet sits level on the head with the front edge above the eyebrows. If using goggles, align them so the Stack Vent of the helmet matches the goggle’s center vent for reduced fogging.
What to consider before purchase
Intended use: urban/recreational riding vs. aggressive downhill
Required level of facial/chin protection
Preferred ventilation control and compatibility with goggles or audio accessories
Usage recommendations
Use the In Form fit dial to fine-tune fit before each ride, close the Thermostat Control vents in cold or wet conditions, and align goggles with the Stack Vent to minimize fogging. Replace the helmet after any significant impact or according to the manufacturer's replacement guidelines.
