Protective winter helmet GIRO STELLAR MIPS, matte graphite, size M (55.5–59 cm)

GIRO STELLAR MIPS in matte graphite, size M (55.5–59 cm) is a protective winter helmet engineered for cold-weather cycling and urban riding. It combines a reinforced outer shell with MIPS rotational-impact technology to reduce rotational forces in certain impacts, while offering an adjustable fit and winter-appropriate ventilation. The helmet is intended for commuters, recreational cyclists and approaches in alpine or mixed-weather environments where thermal comfort and durable protection are required.

Advantages

The helmet integrates MIPS technology to address rotational forces in angled impacts and uses a reinforced shell construction to withstand seasonal use. Adjustable fit features enable secure and individualized sizing within the 55.5–59 cm range, and the matte graphite finish provides low-reflective aesthetics suitable for urban and outdoor settings. Ventilation is balanced to retain warmth while allowing some airflow to prevent overheating during active rides in cold conditions.

Suitable for

• Commuting in cold and variable weather
• Recreational cycling and winter training
• Urban riding and mixed-surface approaches
• Alpine access and short approach hikes to trailheads

Key specifications

• Size range: medium fit for head circumferences approximately 55.5–59 cm
• Shell: reinforced winter-cap construction for seasonal durability
• Impact protection: integrated rotational-impact protection system
• Finish: matte graphite color
• Fit system: adjustable retention mechanism for secure fit
• Ventilation: reduced/opening design optimized for cold-weather use

How to use

Place the helmet on the head so it sits level and low on the forehead, then tighten the retention system until the helmet feels secure but comfortable. Adjust the chin strap to form a snug V-shape under the ears and fasten the buckle; the strap should allow one or two fingers between strap and jaw. Use the ventilation adjustments, if present, to regulate airflow according to temperature and activity level. Inspect the helmet regularly for signs of damage and replace it after a significant impact or if fit components become compromised.

Usage recommendations

For optimal protection and comfort in winter conditions, wear appropriate thermal head layers compatible with the helmet fit and ensure the retention system remains properly adjusted throughout the ride. Replace the helmet after any crash that produces significant impact, and follow manufacturer care instructions to preserve shell integrity and MIPS function.
