The FURY model in the Kilian Jornet Series comes in natural brown hues based on the savage landscapes that Kilian experiences each and every day. The Kilian logo on the lens and top of the frame shows that this model has been worn and validated on the ground, where approximation has no place. Fitted with the SPECTRON 3 Silver Flash lens (cat. 3), it offers reliable and versatile protection in full sun. The flash treatment enhances light filtration while preserving accurate reading of the terrain, keeping vision clear even when the pace ramps up. With a wraparound frame, wide lens and anti-slip inserts on the nose pads and temples, the FURY model stays perfectly in place when the going gets intense. Built for speed.
