This special formula meets both ECE 22.05 and DOT requirements. Hypoallergenic LS2 uses hypoallergenic technical fabrics that wick moisture to help keep you cool while you ride. Laser-Cut Foam Multi-­density foam is cut using LS2 s 3D Laser Technology and formed to fit the curves of the rider s face for a perfect fit with no hot spots. Double D Ring This model uses a classic double D­-ring buckle system for a secure fit. Slide the strap through BOTH D­-rings, and then wrap it over the first and through the second. Pull the strap until you have a snug fit that won t roll off. Emergency Release System The LS2 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. 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 and pull carefully, slipping the pads free. Slide the cheek pads over the straps and pull them away from the helmet. Metal Security Plate This small metal triangle is an LS2 exclusive feature and reinforces the attachment of our 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.
