Fasten the chin strap and adjust the side sliders so that the straps form a V-shape just below your ears. Ensure the buckle is securely clicked into place before starting your ride.

Verify that the helmet fits firmly without excessive movement
Check the strap tension to ensure it does not pinch the skin
