This special formula meets both ECE 22.05 & DOT requirements. Double D Ring This model uses a classic double D?ring buckle system for a secure fit. Slide the strap through both D?rings, & then wrap it over the first & through the second. Pull the strap until you have a snug fit that won t roll off. Emergency Release System The 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 & neck. It is best to have someone hold the helmet to keep it from moving as you remove the pads. Slide your finger into the red loop & pull carefully, slipping the pads free. Slide the cheek pads over the straps & pull them away from the helmet. Metal Security Plate This small metal triangle is an LS2 exclusive feature & reinforces the attachment of the chinstraps to the shell for extra strength. Note Please note that as long as nothing else is written in the article description, all helmets that have a visor as standard will be delivered with a clear one, even if it is shown differently.
