How to use

Place the helmet on your head so that it rests level and covers the forehead without tilting backward. Adjust the retention system until the helmet fits snugly but comfortably; straps should form a V shape under each ear and the chin strap should be fastened with enough tension to hold the helmet securely while allowing you to open your mouth. Inspect padding and straps before each ride and replace the helmet after any significant impact or visible damage.

Usage recommendations

For optimal protection, measure your head circumference before selecting the helmet to ensure the universal L adjustment range is suitable. Clean the helmet padding with mild soap and water and avoid exposure to strong chemicals or high temperatures. Replace the helmet if it shows cracks, crushed foam, or after a substantial collision.
