Key specifications
 Fit range: 51–55 cm (size S)
 Construction: lightweight protective shell designed for impact absorption
 Ventilation: multiple vents for airflow to manage heat during activity
 Retention system: adjustable rear fit mechanism for secure positioning
 Interior: removable or adjustable padding for comfort and moisture management
 Finish: matte harbor blue
 Intended use: trail and cross-country mountain biking, recreational cycling
How to use
Place the helmet on the head so it sits level and covers the forehead without tilting back. Adjust the rear retention system until the helmet feels snug but comfortable; the helmet should not move excessively when you shake your head. Fasten and adjust the chin strap so that it rests under the chin and forms a V-shape around each ear. Replace internal pads or fine-tune strap positions to achieve an even pressure distribution. Inspect the helmet for visible damage before each ride and follow the manufacturer's guidance on service life and replacement after significant impact.
Usage recommendations
Use this helmet for trail and cross-country rides where both protection and a lightweight fit are required. For best results, match the helmet size to your head circumference, maintain clean padding and straps, and replace the helmet after a strong impact or if the shell or liner shows visible damage.
