Julbo Fury Kilian Jornet Spectron 3 Cat Sunglasses

With a 131 mm wide lens and a base curve of 6, the Julbo Fury Kilian Jornet Spectron 3 Cat Sunglasses deliver uncompromising panoramic vision for high-speed endurance sports. Developed in collaboration with legendary mountain runner Kilian Jornet, this special edition combines cutting-edge optics with a featherweight, ventilated frame engineered for the most demanding trails.

Overview

The Fury is built around a full-vented Grilamid TR90 frame that stays cool and fog-free even during intense efforts. Its Spectron 3 polycarbonate lens offers category 3 protection, blocking 100% of UVA, UVB, and UVC rays while the dark smoke tint with red flash mirror reduces glare and enhances contrast on bright alpine terrain. The large fit accommodates a wide range of face shapes, and the Grip Tech temples plus nose grip keep the glasses locked in place through sweat, vibration, and rapid descents.
