The KLIM Rage Goggle is designed to create excellent vision on the snow with quick-change lenses for all conditions. The Rage lens system with slide+hinge lock technology allows you to quickly and easily swap lenses on the fly for changing light conditions. The Rage is engineered with anti-fogging technologies such as air circulation through foam filtered vents, large internal air volume and Super Anti-Fog lens coating.
