Full-frame shades don't have to be bulky, as proven by the Roka CP-1X Sunglasses. The CP-1X weighs in at one single ounce, meaning you won't even notice them on your face while enjoying the protection and improved vision they provide. The Toric Shield single lens provides uninterrupted vision while protecting your eyes from wind and debris coming up from the trail. Roka used C3 optics to ensure that your vision is the best it can be, while coating the lens to help it resist moisture, abrasions, reflections, and fog. The Geko nose and temple pads provide a comfortable yet consistent grip, even in the presence of perspiration, and the CP-1X comes with three nosepieces for a perfect fit.
