Full-face helmet GIRO INSURGENT SPHERICAL MIPS — size M/L (55–59 cm), Matte Hedge Green Dark Shark

The GIRO INSURGENT SPHERICAL MIPS full-face helmet in size M/L (55–59 cm) and Matte Hedge Green Dark Shark finish is designed for trail and enduro riders who need comprehensive head protection with integrated chin-bar coverage. It combines Spherical impact technology with a MIPS rotational protection system to address both linear and angled impacts. The helmet offers an adjustable fit and ventilation features suitable for all‑mountain and off‑road use while preserving a streamlined profile and a durable outer shell.

Advantages

The combination of Spherical technology and MIPS provides layered impact management that separates rotational and linear energy pathways to reduce forces transmitted to the head. The integrated chin-bar and full-face design deliver extended facial and jaw protection compared with open-face helmets. An adjustable fit system ensures the helmet sits securely across the 55–59 cm head circumference range, and the ventilation layout balances airflow and coverage to maintain comfort during technical descents and longer rides.

• Trail riding and enduro routes
• All‑mountain and off‑road cycling
• Technical downhill sections and bike parks
• Riders seeking enhanced rotational impact protection

How to use

Select the helmet if your head measures within the 55–59 cm range and adjust the internal fit system until the helmet feels snug but comfortable. Fasten and adjust the chin strap so that it sits securely beneath the jaw without excessive movement; ensure the buckle is locked. Position the helmet level on your head with the front edge just above the eyebrows to maintain clear vision and proper coverage. Inspect vents and padding before each ride and replace or service components according to manufacturer guidance if you notice damage.

Usage recommendations

Use this full-face helmet for trail, enduro and aggressive all‑mountain riding where additional facial protection and rotational impact mitigation are priorities. Regularly check fit and straps, clean the shell and liners with mild soap and water, and replace the helmet after any significant impact or when signs of wear compromise safety.
