How To Wear the Helmet
① Position the helmet on your head with the front covering your
forehead.
② Position the strap adjuster centered, just below your ears.
③ Position the helmet low on your forehead with the buckle under
the chin and back against the throat. The straps should fit
comfortably around both ears.
④ After removing the chinstrap pad, adjust the chinstrap tension at
the buckle so the chinstrap is tight and comfortable by pulling the
chinstrap end through the buckle to either tighten or loosen as
needed.
