GIRO winter women's helmet STELLAR MIPS size S (52–55.5 cm) matte white

The GIRO STELLAR MIPS size S (52–55.5 cm) in matte white is a women's winter protective helmet engineered for cold-weather cycling and snowsports. It integrates a hard-shell outer construction with impact-attenuating liner and MIPS rotational impact protection to reduce rotational forces in certain crash scenarios. The helmet is sized for a small head circumference range and includes winter-focused comfort features to maintain fit and thermal comfort during outdoor activities.

Advantages

This helmet provides combined linear and rotational impact protection thanks to the integrated MIPS system and energy-absorbing liner. The small size fit system allows fine adjustment for stable positioning on the head, while the matte white finish offers a neutral, low-glare appearance. Winter-oriented design elements improve insulation and compatibility with cold-weather accessories without compromising safety performance.

Suitable for

• Cold-weather cycling and commuter rides in winter conditions
• Recreational alpine skiing, snowboarding and snowsports
• Urban riding and multimodal transport where lightweight head protection is needed

When it may not be suitable

This helmet is sized specifically for small head circumferences (52–55.5 cm) and may not provide a correct fit for larger or smaller heads outside that range. It is designed for recreational and commuter winter use; it is not a substitute for helmets designed and certified for high-speed motorsports or industrial safety applications.

Key specifications

• Intended use: women's winter helmet for cycling and snowsports
• Fit range: 52–55.5 cm (size S)
• Protective system: rotational impact protection integrated (MIPS)
• Shell: hard outer shell with impact-absorbing liner
• Finish: matte white
• Adjustability: internal fit-adjustment system for a secure fit
• Seasonal features: winter comfort and insulation elements

How to use

Place the helmet on your head so it sits level and covers the forehead without tilting back. Use the internal fit-adjustment mechanism to tighten until the helmet feels secure but comfortable; the helmet should not move freely when you shake your head. Fasten and adjust the chin strap so it forms a V-shape under each ear and allows one or two fingers’ space between strap and chin. Before each use check that the MIPS liner and shell are undamaged and that straps and buckles function correctly.

What to consider before purchase

• Measure head circumference accurately to ensure selection of size S (52–55.5 cm).
• Confirm the helmet meets the required safety standards for your intended activity and region.
• Consider compatibility with goggles, a balaclava, or winter liners for additional warmth and comfort.

Usage recommendations

For best protection and comfort in winter conditions, pair the helmet with a thin moisture-wicking liner or skullcap to maintain warmth without affecting fit, and replace the helmet after any significant impact or if visible damage is present.
