Product information

Description

The GIRO Ratio Mips is an open-face helmet designed for urban and recreational cycling, combining a hard-shell construction with the Mips rotational energy management system. It offers adjustable fit with the In Form fit system, targeted ventilation through Stack Vent and Thermostat Control, and a matt finish. The helmet is compatible with Giro goggles and aftermarket audio systems, and its construction balances durability and weight for everyday use.

Advantages

The Ratio Mips integrates a low-profile Mips slip plane to help reduce rotational forces in certain impacts, while the hard-shell with an in-mold lower wrap provides durable protection without excessive weight. Thermostat Control adjustable venting and Stack Vent alignment reduce fogging and allow quick airflow adjustment, and the In Form Fit System delivers fast, precise sizing and improved stability.

Suitable for

  • Urban commuting and city cycling
  • Leisure and recreational rides
  • Riders who prefer an open-face, hard-shell helmet
  • Users who want compatibility with Giro goggles and aftermarket audio systems

When it may not be suitable

This open-face helmet does not provide full-face coverage, so it may not be appropriate for aggressive downhill riding or motorized sports that require full-face protection. Riders seeking the lightest possible road racing shell may find the hard-shell construction heavier than some in-mold-only designs.

Key specifications

  • Helmet type: Open-face, hard-shell with in-mold hardbody lower wrap
  • Protective technology: Integrated Mips rotational energy management
  • Fit system: In Form Fit System with ergonomic dial (up to 6 cm adjustment)
  • Ventilation: Stack Vent alignment and Thermostat Control adjustable venting
  • Compatibility: Designed to work with Giro goggles; compatible with select aftermarket audio systems
  • Finish: Matt

How to use

Place the helmet on your head and use the In Form dial at the base to fine-tune the fit until the helmet sits securely and comfortably. Use the Thermostat Control button to open or close vents and adjust airflow as conditions change. Align goggles with the helmet so the Stack Vent and goggle center vent match to reduce fogging. Regularly check straps and fit before each ride and replace the helmet after any significant impact.

What to consider before purchase

  • Intended use: open-face design is suited to commuting and recreational cycling, not full-face protection
  • Head size and fit: verify sizing range to ensure correct fit and comfort
  • Ventilation needs: Thermostat Control and Stack Vent help manage airflow and reduce goggle fogging
  • Compatibility with goggles and audio accessories if required

Usage recommendations

For best performance, pair the GIRO Ratio Mips with Giro goggles, set the In Form dial for a snug fit, and use the Thermostat Control to adapt ventilation to weather and activity level. Replace the helmet after any significant impact and follow manufacturer care instructions.
