Remove the liner and cheek pads and hand wash with normal detergent in cold water. Let them air dry. Do not use a washing machine or tumble dry. Hand wash and air dry only. To remove the cheek pads, gently pull the padding off from the three snap buttons holding it in place and pull out the retaining flap from underneath the lower helmet beading. To remove the liner, unsnap the rear portion of the inner located towards the rear of the helmet. Gently pull out the liner without forcing the liner out from its front clips located at the top portion of the visor opening. Reverse the steps to reinstall liner.
