This FASTER L edition is inspired by the blues of the Norwegian glaciers where Kilian Jornet lives, trains and explores. A cool and intense shade, reflecting a savage land shaped by wind, ice and no room for compromise. The meaning of the Kilian logo on the lens and top of the frame is much more than just another color: it represents a partnership built over time, based on real-life performance with no place for error. Fitted with the REACTIV 0-3 High Contrast lens (cat. 0 to 3), it transitions seamlessly from darkness to full sunlight. The translucent base tint accentuates relief and refines reading of the terrain, even when the light is less bright. Ideal for early morning starts, exposed summits and long outings in changing conditions. A frame defined by the terrain. With nothing left to chance.

Bio-Based — This model is primarily made from a plant-based material derived from castor beans. The team at Julbo uses Rilsan®, a high-performance material known for its lightweight feel, flexibility, and durability. It helps reduce the use of fossil-based materials while maintaining the technical standards you expect from a Julbo frame. More responsible. Just as high-performing.

Optical Clip Compatible — This model can be adapted to your vision thanks to an optical clip that fits securely inside the frame. The clip allows you to enjoy full Julbo sun performance while keeping your prescription. Lightweight and discreet, it delivers stable, comfortable vision for sport, without compromising fit or field of view. 

REACTIV — Julbo’s most advanced lens technology, tailored to every need through a range of specialized treatments. The lens instantly adapts to all weather conditions.

REACTIV lenses automatically adapt to changing light conditions. The brighter the sun, the darker they get. As light fades, they lighten. This ensures consistently comfortable, high-performance vision, without needing to switch eyewear, whatever the conditions. Ideal for activities where light changes quickly: mountain sports, trail running, cycling, or skiing.
