Winter Helmet GIRO TRIG MIPS by GIRO, model TRIG MIPS, size L (59–62.5 cm), matte stone, new 2025/2026

The GIRO TRIG MIPS winter helmet in matte stone (size L, 59–62.5 cm) is a cold-weather protective helmet engineered for cycling and light snow-sport use. The helmet integrates a multi-directional impact protection system (MIPS) to reduce rotational forces in certain impacts, and offers a fit range suitable for larger head sizes. Designed for the 2025/2026 season, the TRIG MIPS combines winter-ready coverage with ventilation and an adjustable fit system to balance warmth and breathability during commuting, touring, and recreational winter riding.

Advantages

The helmet provides extended coverage around the head to protect against impacts typical in urban and off-road winter environments. The built-in MIPS layer aims to reduce rotational forces transmitted to the head during angled impacts. Its adjustable retention system and padding allow for a secure fit in the 59–62.5 cm range, while the matte stone finish gives a low-reflective, understated appearance. Materials and construction focus on a lightweight but insulated design appropriate for cold conditions without adding excessive bulk.

Suitable for

• Cold-weather cycling, including commuting and urban riding.
• Winter touring and multi-hour rides where additional head coverage and insulation are needed.
• Recreational snow-sports and mixed-surface activities that require impact protection and a secure fit.

When it may not be suitable

The GIRO TRIG MIPS is intended for cycling and light snow-sport activities; it is not certified as a full-contact ski or snowboard race helmet or for motorized vehicle use. Users requiring specialized ventilation for high-intensity summer riding or minimal weight for competitive road racing may find this winter-oriented model heavier and warmer than dedicated summer helmets.

Key specifications

• Size range: L, fits head circumferences approximately 59–62.5 cm.
• Protective system: multi-directional impact protection layer to address rotational forces.
• Finish: matte stone color with low-reflective surface.
• Seasonal use: designed for cold-weather conditions with added coverage and insulation features.
• Adjustability: integrated retention system and internal padding for a tailored fit.

How to use

Measure head circumference to confirm the helmet fits within the 59–62.5 cm range before purchase. Adjust the retention dial and internal padding so the helmet sits level on the head and the front edge is approximately one to two finger-widths above the eyebrows. Fasten and adjust the chin strap to be snug but comfortable; straps should form a V-shape under each ear. Use the helmet for winter rides, ensuring vents and fit are adjusted to balance warmth and airflow. Inspect the helmet regularly for signs of wear or damage and replace it after any significant impact.

What to consider before purchase

• Confirm head circumference measurement matches the helmet size range (59–62.5 cm).
• Determine whether a winter-specific helmet with added insulation is appropriate for your riding intensity and local climate.
• Check compatibility with any eyewear, goggles, or communication accessories you plan to use.

Usage recommendations

For best protection, replace the helmet after a significant impact and follow manufacturer care instructions. Use this helmet for commuting and recreational winter activities where additional coverage and rotational-impact mitigation are priorities; pair it with appropriate cold-weather clothing and visibility accessories when riding in low-light conditions.
