Engineered for high-performance trail running, the SKYRUN is built to excel across every terrain—from fast forest singletrack to exposed alpine ridgelines. At just 28 grams, its ultra-light cylindrical design delivers a featherweight feel without compromising stability when the pace intensifies. Thermogrip® inserts on the temples and nose ensure a locked-in fit through steep climbs, aggressive descents, and technical sections, while the adjustable nose bridge provides a precise, personalized hold that remains secure over long distances. At the core of SKYRUN’s performance is its advanced lens technology. Equipped with PHANTOM photochromic lenses (Cat. 0 to 3), the lens adapts instantly to changing light conditions—enhancing contrast, sharpening terrain definition, and reducing visual fatigue so you can react faster and maintain peak efficiency. Bollé’s anti-fog expertise ensures consistently clear vision during sustained effort, even in humid, high-output conditions. Developed, tested, and validated by our team of trail athletes, the SKYRUN is built to perform in the harshest environments—delivering uncompromising protection, precision, and performance when it matters most.
