Fully adjustable temples and nose piece make it easy for you to find a secure and comfortable fit, no matter your head shape or size. And with a frame design that maximizes peripheral vision, it's easy to see every detail on the trails or on the road. Clarity lens technology controls the color spectrum and is fine-tuned for different riding environments. Trail lenses sharpen greens and browns, while road lenses use a violet base tint to improve definition on the road. The Clarity lenses are easy to swap, so you can use the same frame with different lenses depending on if you choose to ride the trail or on the road.
