 Color: navy
 Fit system: adjustable retention mechanism for secure fit

How to use
Place the helmet on your head so it sits level and covers the forehead without tipping backward or forward. Adjust the retention system until the helmet feels snug but not uncomfortable; use the chin straps to secure the helmet and fasten the buckle, adjusting strap lengths so they form a V under each ear. Check that the helmet does not move excessively when you shake your head. Replace padding or readjust the fit as needed for comfort and stability.
