Sunglasses

Wearing sunglasses while trail running is essential to protect your eyes from several challenges: intense sunlight, high-altitude UV rays, reflections on snow or rock, dust, wind, or splashes (dirt, sand, etc.). Suitable glasses also help reduce eye strain, improve running comfort, and increase safety by maintaining good visibility on the trail, whatever the surroundings.

For trail running, often in the mountains, on paths, with strong changes in light, choose lightweight glasses, well ventilated, with a good fit (stable nose and arms) and a wide field of vision. The type of lenses is important: photochromic lenses or those with high sun protection allow adaptation to changing brightness. The glasses must also be shock- and chip-resistant, and remain comfortable even after several hours of effort.

The R-LIGHT SUN combines lightness, comfort, and technical skill: its lenses are available in photochromic 1-3 version (automatically adjusting to brightness) or in category 3 version for intense sunlight.
The design is made for trail running: lightweight frame, adjustable nose bridge, flexible and grippy arms, which ensure a good hold even in motion.
Thanks to their UV400 protection, they shield your eyes from harmful rays while offering clear and comfortable vision both in the mountains and on the plains.

Category 3 lenses are especially suitable for outings in full sunlight, at high altitude, on snow, or on very bright terrain: they provide strong light filtering to protect the eyes from UV rays and glare.

Photochromic lenses 1-3 are the versatile option: they adjust automatically to the brightness, making them very handy for trails with changing weather or quick shifts in exposure (forest, mountain, shaded/sunny sections). This adaptability makes them a good choice for long outings or ultras, where conditions can change greatly.
