For additional initial adjustment, use the metal slider buckle on the strap with the ribbed plastic tab to take up excess strap. Emergency Release System - LS2\'s emergency release system allows emergency responders to remove the cheek pads from the helmet, allowing extra space to remove the helmet with minimal movement of a fallen rider\'s head and neck.
