Designed for speed and built for endurance, the Julbo Intensity REACTIV Sunglasses are made for athletes who move fast and demand uncompromising vision. Whether you’re hammering gravel miles or pushing the pace on technical trails, these ultra-light performance sunglasses deliver exceptional clarity, ventilation and comfort.

At just 19 grams, the Intensity is built to disappear on your face while providing a secure, stable fit. The large panoramic lens offers an expansive field of vision so you can stay focused on the terrain ahead, while strategically placed front venting keeps air flowing to reduce fogging during high-output efforts.

The REACTIV 1-3 Light Amplifier photochromic lens automatically adjusts to changing light conditions, brightening in low light and darkening when the sun comes out. This makes the Intensity an ideal companion for mixed conditions, early morning starts, forested trails or long days on the bike.

Slim, flexible temples and Julbo’s Grip Tech material keep the glasses comfortably locked in place without pulling hair or creating pressure points. Designed to integrate seamlessly with helmets, the Intensity stays secure even when the effort ramps up.

Light, fast and built for performance, the Intensity lets you focus on the ride or the run, not your eyewear.

REACTIV 1-3 - Light Amplifier: Photochromic lenses (cat. 1 to 3 - visible light transmission rate: 17% - 75%), they get darker or lighter to match changing light conditions and therefore adapt to any time of day and to the terrain. Internal anti-fog coating and external oil-repellent coating (prevents marking, makes cleaning easier and facilitates water runoff). Ideal for trail running, cycling, and mountain biking.
