Road and trail riding demand the most from you and your equipment, where crystal-clear vision is paramount to success on the road or trail. The Bolle Draft's B-Clear lenses enhance your ability to see what's coming at you, and whom you've left behind. Photochromic lenses adjust with exposure to various light conditions, and offer enhanced contrast in both the light rose and dark rose state. A silver flash mirror reflects glare improving visual acuity in the brightest conditions. Special Thermogrip technology keeps your glasses comfortably and securely positioned using a hydrophilic nose pad and temple tips, whose grip increases as you sweat. The adjustable nose pad can be tailored for a custom fit. The lightweight Crystal Smoke nylon frame is incredibly durable and flexible. Includes hard case and soft lens cloth.
