Twin Shield System LS2 s drop-down sun shield helps protect the rider s eyes from bright sun, and moves up and out of the way quickly and easily when entering dark tunnels, offering a more comfortable riding experience. 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. Emergency Release System Our 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.
