Julbo Shield Kilian Jornet Reactiv

Designed for maximum protection in the mountains. The large lens and detachable side shields protect against bright light, wind, and reflections when you are active above the tree line for extended periods.

Adapts to virtually all lighting conditions. The lens remains clear in dark passages and offers strong protection as soon as you emerge onto open terrain with bright sun and glare.

You notice the difference especially during long days in the mountains. When transitioning from forest to ridge, during early starts, or on high-altitude routes with a lot of glare, you don't have to constantly switch glasses to maintain comfortable vision.

Are you hesitating between these and standard photochromic sports glasses? Choose these if you regularly venture into high mountains or very open terrain. Do not choose these if you mainly walk on sheltered forest trails where maximum light protection is rarely needed.
