Julbo Frequency REACTIV 1-3 - Light Amplifier
The Julbo FREQUENCY sunglasses are built for moving fast. Designed for cyclists and trail runners who like to push the pace, they combine streamlined style with high-performance protection for long days on the road or trail.
A wide panoramic lens delivers an expansive field of view, helping you stay aware of the terrain, the trail ahead, and everything happening around you. Whether youāre descending singletrack or picking up speed on open roads, the FREQUENCY keeps your vision clear and unobstructed.
The lightweight frame is engineered to stay comfortably in place without pressure or unwanted sticking points, even when the effort ramps up. Up front, an integrated ventilation system promotes airflow to reduce fogging, keeping your vision sharp during intense climbs and fast descents.
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.
