Protective helmet GIRO Manifest MIPS Spherical — size M (55–59 cm), Matte White Black

The GIRO Manifest MIPS Spherical in size M (55–59 cm) is a full-coverage mountain-bike helmet designed for trail and enduro riding. It combines a robust outer shell with GIRO’s Spherical impact-management construction and MIPS rotational protection to reduce rotational forces during oblique impacts. Matte White Black finish provides a neutral, low-glare appearance while adjustable fit features ensure stable seating and consistent coverage for off-road conditions.

Advantages

This helmet integrates Spherical construction and MIPS rotational technology to address both linear and rotational impact vectors without compromising ventilation or fit. The full-coverage shell offers extended protection around the temples and occipital area, and internal fit adjustments allow the helmet to be tuned for a secure, comfortable fit during aggressive riding. The Matte White Black color balances visibility and understated styling suitable for a wide range of riding gear.

Suitable for

• Trail riding and enduro courses where extended coverage and impact management are required
• All-mountain sessions with varied terrain and higher-speed descents
• Riders seeking certified crash protection with adjustable fit for long rides

Key specifications

• Size: M, fits head circumferences 55–59 cm
• Protection system: Spherical impact-management construction combined with MIPS rotational protection
• Shell type: Full-coverage shell optimized for trail and enduro use
• Ventilation: Multiple vents and internal channels for airflow during active riding

How to use

Place the helmet on the head so it sits level and covers the forehead without tilting back. Adjust the internal retention system until the helmet feels snug but not tight; the helmet should not move independently from the head when you shake it gently. Fasten and adjust the chin strap so it forms a comfortable V under each ear and allows one or two fingers’ width between the strap and the chin. Periodically inspect the helmet for visible damage, proper strap function, and retention integrity; replace after any significant impact or if structural damage is detected.

Usage recommendations

Use this helmet for trail and enduro riding where greater coverage and rotational protection are beneficial. Ensure the size M fit (55–59 cm) matches your head circumference before purchase. Replace the helmet after a significant crash or when signs of wear compromise protective function.
