How to use

Use the SELFIT 5‑step fitting system to adjust the internal cradle until the helmet feels stable without excessive pressure. Fasten the buckle clasp and adjust the chin straps so they form a V‑shape below the ears; the strap should be snug but allow comfortable movement and full jaw opening. Before each ride, check that the helmet fit is secure and that straps and clasp are undamaged.

Usage recommendations

Check the fit of the helmet before each use and replace the helmet after any significant impact or according to the manufacturer’s safety guidance. Clean the helmet with mild soap and water and avoid exposure to strong solvents or prolonged direct sunlight when stored.
