Product information

Description

The GIRO Ratio Mips open-face helmet combines hard-shell durability with Mips rotational protection and an adjustable In Form fit system. Its Stack Vent ventilation and Thermostat Control allow fast, simple airflow adjustment, while a matt finish reduces glare. Designed for urban and recreational cycling, the Ratio offers dependable head protection, compatibility with Giro goggles and optional aftermarket audio systems.

Advantages

The helmet integrates a Mips slip plane to help reduce rotational forces in certain impacts and features a two-piece hard-shell construction with a polycarbonate lower wrap for durability without excessive weight. The In Form fit system provides up to 6 cm of quick, tool-free adjustment for a secure fit, and Stack Vent alignment with goggle vents helps reduce fogging. Thermostat Control gives immediate, low-profile vent control for on-the-go comfort.

Suitable for

  • Urban commuting and city cycling
  • Recreational rides and light touring
  • Riders looking for a low-profile open-face helmet with adjustable ventilation
  • Users who want compatibility with Giro goggles and aftermarket audio systems

When it may not be suitable

The open-face design does not provide full-face coverage required for downhill mountain biking or motorized sports. Riders seeking maximum chin and face protection or a full-face helmet should consider specific full-coverage models instead.

Key specifications

  • Shell type: two-piece hard shell with in-mold polycarbonate lower wrap
  • Protection system: Integrated Mips slip-plane rotational protection
  • Fit system: In Form dial-fit with up to 6 cm adjustment
  • Ventilation: Stack Vent plus Thermostat Control adjustable venting
  • Finish: matt
  • Compatibility: designed to interface with Giro goggles; compatible with some aftermarket audio systems

How to use

Place the helmet level on your head and fasten the chin strap so it sits snugly beneath the chin. Use the In Form dial at the back to fine-tune fit—turn until the helmet feels secure without pressure points. Adjust the Thermostat Control button to open or close vents for desired airflow. Align goggles with the helmet’s Stack Vent to reduce fogging and attach compatible audio accessories if required following the accessory manufacturer’s instructions.

What to consider before purchase

  • Choose the correct size for head circumference to ensure proper fit and safety
  • Open-face design is not suitable for activities needing chin or face protection
  • Check compatibility if you plan to use specific aftermarket audio systems

Usage recommendations

Inspect the helmet regularly for signs of damage and replace it after any significant impact. Clean with mild soap and water and avoid solvents that can degrade materials. Follow Giro and accessory manufacturers’ instructions for proper fit and accessory installation.
