Road Helmet GIRO HELIOS SPHERICAL MIPS size L (59–63 cm) matte sharkskin

The GIRO HELIOS SPHERICAL MIPS size L (59–63 cm) matte sharkskin is a road cycling helmet engineered to combine lightweight construction, extensive ventilation and integrated rotational impact protection. Its Spherical impact management system works together with MIPS technology to reduce rotational forces in angled impacts, while the shell shape and internal channels prioritize airflow for longer efforts. The helmet fits head circumferences from 59 to 63 cm and features an adjustable retention system for a stable, customizable fit during training, long rides and competitive events.

Advantages

This helmet offers a balance of low weight and targeted ventilation to maintain rider comfort over extended distances. Integrated Spherical impact protection and MIPS rotational technology provide layered safety features that address both linear and rotational impacts. The adjustable fit system and size-specific shell ensure secure positioning and reduced movement, and the matte sharkskin finish gives a subdued aesthetic while resisting minor abrasion. Designed for road use, the helmet optimizes airflow and minimizes bulk to reduce fatigue without compromising protection.

Suitable for

• Road training sessions and endurance rides
• Group rides and club events
• Road racing and time trials
• Commuting on paved routes where light weight and ventilation are preferred

Key specifications

• Head size range: 59–63 cm (size L)
• Construction: lightweight road helmet shell with internal impact liner
• Impact systems: Spherical impact management combined with rotational MIPS technology
• Finish: matte sharkskin color
• Ventilation: multiple large vents with internal channeling for airflow
• Fit adjustment: dial-type retention system with height and strap adjustment
• Weight: lightweight category for road helmets (manufacturer specification varies by exact configuration)

How to use

Place the helmet on the head so it sits level, covering the forehead without tilting back. Adjust the dial retention until the helmet feels secure but comfortable, and position the straps to form a V just below the ears. Fasten the chin strap and tighten so that no more than two fingers fit between the strap and the chin. Inspect the helmet for proper seating and minimal movement before each ride. Replace the helmet after any significant impact or if the shell or liner show visible damage.

Usage recommendations

For best performance, pair the helmet with eyewear and breathable cycling clothing to maximize ventilation. Periodically check strap condition and retention components for wear; clean the shell and pads with mild soap and water. Do not use chemicals or solvents that could degrade the liner or finish.
