The helmet features an adjustable fit system and ventilation channels to balance protection and airflow for recreational and commuter cyclists.

Advantages

Its shell and EPS liner deliver reliable impact attenuation for everyday mountain biking and commuting. Vented construction improves airflow to reduce overheating on longer rides while retaining protective performance. The design maintains a balance between lightweight construction and robust protection.

How to use

Place the helmet level on the head so the front edge sits just above the eyebrows, then adjust the retention system until the helmet feels secure but comfortable. Fasten and adjust the chin strap so it forms a V-shape under each ear and allows one or two fingers’ space between strap and chin. Check that the helmet does not tilt forward or backward and that straps are snug. Inspect the helmet before each ride for cracks or damage and replace it after a significant impact.

Usage recommendations

Use the helmet for mountain biking, trail riding and urban commuting where typical MTB coverage is required. Clean the shell with mild soap and water; avoid solvents or harsh chemicals. Store the helmet in a dry place away from direct sunlight and excessive heat. Replace the helmet if it has sustained a strong impact, shows visible damage, or no longer provides a secure fit.
