Winter Helmet GIRO RATIO MIPS — brand GIRO, model RATIO MIPS, size L (59–62.5 cm), matte indigo, new 2025/2026

GIRO RATIO MIPS is a winter helmet designed for protection and comfort during cold-weather riding and snowsports. Finished in matte indigo and sized L (59–62.5 cm), this 2025/2026 model integrates rotational-impact mitigation technology alongside a fit system and thermal features intended to balance safety, warmth and stability on the hill or trail.

Advantages

The helmet combines a hard outer shell with an inner energy-absorbing liner and an integrated MIPS layer to reduce rotational forces in certain impacts. The adjustable fit system allows precise sizing across the L range for a secure hold, while ventilation and ear/liner design aim to retain warmth without excessive bulk. The matte indigo finish provides a low-reflective, neutral appearance suitable for a range of winter outfits and equipment.

Suitable for

• Skiing and snowboarding at resorts or backcountry where certified protective gear is required
• Winter cycling or commuter riding in cold conditions demanding combined protection and insulation
• All-day cold-weather outdoor activities where a stable, adjustable helmet fit is needed

When it may not be suitable

This helmet is intended for winter sports and cold-weather cycling; it may be less suitable for summer cycling or activities where maximum ventilation is essential. It is sized for head circumferences of 59–62.5 cm; users outside that range should select a different size. While MIPS can reduce certain rotational forces, no helmet can prevent all types of injury.

Key specifications

• Fit range: Large, fits head circumferences approximately 59–62.5 cm
• Protective system: Integrated rotational-impact mitigation layer
• Construction: Hard outer shell with energy-absorbing inner liner
• Finish: Matte indigo
• Seasonal use: Designed for winter and cold-weather activities
• Adjustability: Internal fit adjustment system for secure positioning
• Thermal features: Designed to retain warmth with ear coverage/liner integration

How to use

Place the helmet level on the head so that the front edge sits just above the eyebrows and adjust the internal fit system until the helmet feels snug but comfortable. Fasten and adjust the chin strap to leave room for one or two fingers between the strap and the chin. Use any removable liners or ear covers according to the weather: keep them fitted in cold conditions and remove or open vents where applicable if temperatures rise. Inspect the helmet before each use for visible damage and replace it after significant impact or according to manufacturer guidance.

What to consider before purchase

• Measure head circumference to confirm the 59–62.5 cm fit range suits you
• Decide whether integrated rotational-impact protection is a priority for your activities
• Consider compatibility with goggles, helmet-mounted audio, or eyewear
• Evaluate whether the helmet’s thermal balance and ventilation match your typical conditions

Usage recommendations

For optimal protection and comfort, pair the helmet with properly fitting goggles, adjust the fit system each time you wear it, and replace the helmet after any significant impact. Store the helmet in a cool, dry place away from direct sunlight and chemicals to preserve materials and finish.
