Winter women's helmet GIRO TERRA MIPS, matte white, size M (55.5–59 cm), model 2025/2026

The GIRO TERRA MIPS in matte white is a women's winter helmet sized M to fit head circumferences of 55.5–59 cm. Designed for cold-weather cycling and light snow-sport use, this 2025/2026 model integrates MIPS technology to reduce rotational forces during impacts, a winter-oriented liner for thermal comfort, and an adjustable retention system for a secure fit. The finish is matte white and the helmet balances insulation with ventilation to maintain comfort during active winter use.

Advantages

The integrated MIPS layer is intended to mitigate rotational forces in the event of an oblique impact, while the adjustable retention system allows fine tuning for a stable fit. The winter liner provides insulation against low temperatures and is compatible with cold-weather use without excessively restricting airflow. The matte white exterior offers a neutral appearance that is easy to pair with winter outerwear.

Suitable for

• Cold-weather road and gravel cycling
• Commuting in winter conditions
• Recreational snow-biking and light snow-sport activities
• Riders needing a helmet sized for 55.5–59 cm head circumference

When it may not be suitable

This helmet is optimized for winter cycling and similar cold-weather activities and may not be ideal for high-speed alpine skiing or aggressive downhill mountain biking where sport-specific helmets with additional face protection and different impact standards are recommended. If you require maximum ventilation for hot-weather riding or the smallest possible weight for race use, a summer-specific lightweight helmet may be more appropriate.

Key specifications

• Fit size: Medium, designed for 55.5–59 cm head circumference
• Technology: MIPS (rotational impact mitigation system)
• Finish: Matte white
• Season: Winter-oriented liner and insulation balance
• Retention: Adjustable fit system for precise sizing
• Ventilation: Balanced vents suitable for cold conditions

How to use

Place the helmet on the head so it sits level and covers the forehead without tilting back. Adjust the retention system until the helmet feels snug but comfortable, then fasten and adjust the chin strap so it forms a V-shape under the ears and closes securely. Use the internal liner for warmth; remove or replace washable liners according to manufacturer care instructions. Inspect the helmet before each use for any visible damage or wear and replace it after significant impact or according to the manufacturer's recommended service life.

What to consider before purchase

• Measure your head circumference to confirm a 55.5–59 cm (M) fit.
• Consider the level of insulation and ventilation you need for your typical winter conditions.
• Verify compatibility with any eyewear, neck gaiters, or helmet accessories you plan to use.
• Check the helmet's certification and intended use to ensure it meets your activity's safety requirements.

Usage recommendations

For winter cycling, pair the helmet with a thin thermal cap or headband if temperatures are very low, and maintain a snug fit to ensure MIPS can function as designed. Clean the outer shell with a mild cloth and follow care instructions for the liner to preserve insulation and hygiene.
