Julbo Aerospeed Sunglasses

From Julbo, a French company that’s been making mountain eye protection for more than 125 years, the Aerospeed sunglasses are well suited for ultrarunning, mountain biking, trail running, and more. The extra-wide lenses offer a broad field of vision and feature an aerated construction that prevents fogging. The Air Link temple system delivers snug all-day comfort without weighing you down, while the 3D-fit nose piece has unique wingtips that can be adjusted in every direction for a better fit. The flexible Grip Tech inserts adhere to the temples so the glasses won’t ride up or shift during high speeds. Finally, the REACTIV lenses have a photochromic finish that adjusts to changing light, while the Spectron 3CF lenses have a glare-resistant flash coating to keep you focused in all conditions.

Named for its founder, Jules Baud, Julbo has its roots in the Jura region of France, dating all the way back to 1888. Baud started out designing optical eyewear, and at the request of crystal hunters braving the mountains of Chamonix, began making protective sunglasses for the most extreme conditions. In the 1950s, the company revolutionized the market with the Vermont glacier sunglasses, built for mountaineers conquering the highest peaks in the world. And that’s exactly where Julbo tested its products—on 8,000ers like K2, Gasherbrum II, Broad Peak, and Nanga Parbat, among others. In the ‘90s and early aughts, Julbo expanded its line to include a wide range of sports and terrains, and today it even makes eyewear for children.
