The INTENSITY model in the Kilian Jornet Series comes in understated and powerful earthy tones inspired by Nordic landscapes. A carefully mastered look, consistent with a vision of performance where every detail counts. The Kilian Jornet logo on the lens and top of the frame symbolizes a collaborative venture based on the demands of the terrain and reliability in movement. Fitted with the REACTIV 1-3 High Contrast lens (cat. 1 to 3), it transitions seamlessly from moderate brightness to full sunlight. The lens accentuates relief and refines reading of the terrain to accompany changes in light without loss of precision. Designed for sustained effort, whether uphill or down, its ultra-light construction disappears on your face, while grippy inserts at the temples and nose ensure it stays perfectly in place.
