Julbo Shield Kilian Jornet Cat 0-4

Inspired by the uncompromising mountain pursuits of Kilian Jornet, the Julbo Shield Kilian Jornet REACTIV sunglasses deliver exceptional protection for everything from alpine ridges and glacier crossings to long days on exposed mountain trails. Featuring Julbo's advanced REACTIV 0-4 High Contrast photochromic lens, they automatically adapt to changing light conditions, transitioning from virtually clear in low light to Category 4 protection in intense alpine sun. Removable side shields block glare, wind and spindrift, while integrated ventilation helps prevent fogging during high-output efforts. Lightweight at just 30g and built with secure Grip Tech temples and a non-slip nose piece, the Shield stays comfortably in place whether you're scrambling rocky arêtes, moving fast across the fells or tackling technical mountaineering objectives. Constructed from durable bio-based materials and designed for demanding mountain environments, these are the ultimate sunglasses for athletes who refuse to slow down when conditions change.

REACTIV High Contrast 0-4 Lenses: (Cat. 0-4 - with a visible light transmission of 4-86%) The lens gets darker or lighter to match changing light conditions, offering the maximum protection at altitude by eliminating the sun's blinding light. The transition to Cat 0 provides a clear, translucent lens for poor light conditions in the morning or evening. Ideal for sensitive eyes and changing weather. The use of High Contrast makes it really easy to identify changing terrain in mixed light conditions, so you can move faster.
