The SCOTT Split OTG Light Sensitive Goggle offers the latest “over the glasses” goggle performance and technology. It features SCOTT’s RAM Air technology to help reduce steaming up on your prescription eyewear and comes with a light sensitive lens. This lens reacts to light changes and within seconds the lens will darken when the brightness gets stronger or lighten when the sunlight gets weaker. The Split OTG was specifically engineered to fit comfortably over prescription eyewear.
