The Cobra snowmobile shields are offered in different heights and looks to give you a shield that matches your riding style and desired level of wind protection. The height of shields are measured from the point where the shield meets the hood straight up to the tallest point. Cobra shields are made from premium, optical-grade polycarbonate for a brilliant surface and distortion free viewing. Materials of 0.80 inch are used for a more durable, longer lasting shield.
