Fitment & Maintenance Information
For maximum protection, a precise fit is mandatory. This X-Small model is part of a 6-size range (XS–XXL) utilizing two dedicated shell sizes to ensure an optimized weight-to-size ratio. The Snell Foundation recommends replacing your racing helmet every five (5) years from the date of manufacture, as protective performance can diminish over time.
To maintain the shell and the White finish, clean only with a soft microfiber cloth and mild soap. Avoid harsh chemicals and solvents, as they can compromise the impact-absorbing EPS liner. Always store your SD1 in a dry, protected helmet bag between races to preserve its lightweight structure and finish.
