## Long description

GIRO Synthe cycling helmet in black, size M/L, is a road-specific helmet designed to balance low weight, ventilation and eyewear compatibility. The shell and ventilation channels promote airflow to help regulate temperature on long rides, while the adjustable fit system secures the helmet comfortably on a range of head shapes. The helmet's design integrates features to accommodate cycling sunglasses and prescription eyewear without compromising fit or safety.
Advantages
The helmet combines a lightweight construction with purposeful ventilation, reducing rider fatigue and supporting sustained performance. An adjustable fit system provides incremental sizing for a secure, consistent fit and helps stabilize the helmet during dynamic movements. Eyewear compatibility makes it easier to store glasses when not worn and reduces interference between frames and helmet contours. The neutral black finish offers a low-profile appearance suitable for a variety of kit styles.
Suitable for
 Road cycling and training rides
 Long-distance endurance events
 Group rides and club sessions
 Riders who regularly use cycling sunglasses or prescription eyewear

How to use
Position the helmet level on the head so the front edge sits just above the eyebrows. Use the adjustable retention dial to tighten or loosen the fit until the helmet feels secure without excessive pressure. Adjust the side straps to form a stable Y-shape around each ear and fasten the chin strap, leaving enough space to insert one or two fingers between the strap and the chin. When using sunglasses, place them on the face first and then don the helmet, or slide the temple arms into the helmet’s eyewear retention areas if available. Periodically check fit before rides and after any impact.
Usage recommendations
Inspect the helmet regularly for signs of wear or damage and replace it after a major impact even if no visible cracks appear. Clean the helmet with mild soap and water, avoid solvents or abrasive cleaners, and store it away from direct sunlight and extreme heat to maintain material integrity. Choose the correct M/L size according to head circumference for optimal protection.
