Julbo Millenium REACTIV 2-4 Polarized sunglasses combine iconic glacier design with advanced optical performance. Photochromic lenses shift from category 2 to 4 depending on UV intensity, while polarization reduces glare from snow, water and rocky terrain to improve contrast and visual comfort.

Removable leather side shields offer full lateral protection in high-altitude environments. The lightweight wrap-around frame with Grip Tech temples and flexible Grip Nose ensures secure fit during intense activity.
