The cylindrical lens has flat optics and offers excellent peripheral vision. The goggles are equipped with a system that enables the fastest, smoothest and safest lens change. A seamless and secure seal between the lens and frame offers unrivaled shape retention. The size-adjustable strap makes the JAM model suitable for all helmets.
