The Scott Spur light sensitive sunglasses are a step further in performance eyewear. The light-sensitive photochromic lens is self-tinting and automatically adjusts to the intensity of sunlight, making it ideal for all weather conditions. The innovative design with XL glass, which creates a perfect shield, is largely focused on protection. The low-profile sides are specially designed to fit well with helmets and offer optimum comfort. The Scott Spur also features the Elc system, which allows you to switch lenses quickly and easily.
