Anything referencing Chamonix is bound to have some serious alpine cred attached to it, so it's no surprise that Julbo's Cham Spectron Sunglasses deliver serious performance during peak-bagging missions and multi-day objectives. The Spectron 4 lens blocks 100% of UV rays and 95% of visible light, making these shades ideal for long, intense exposure high up in the mountains. Leather side shields block peripheral light that sneaks in while you're wandering across glaciers, and the adjustable temples let you dial in a custom, snug fit that won't fly off your face while you're ripping down couloirs or getting pummeled by the wind on exposed ridges.
