The Clarity lens technology controls the colour spectrum and is fine-tuned for use on the track, sharpening the greens and browns associated with this driving environment, while providing complete UV protection. A Ri-Pel lens treatment protects against dirt, oil and water, and an anti-rep coating ensures that your vision is always at its best. The lenses are easy to change and an extra clear lens is included, making the sunglasses ideal for use in a wide range of driving conditions.
