DESCRIPTION

Before you can summit, your approach takes you through high-desert foothills, a mid-mountain pine forest, and high-alpine snowfields. Julbo's Bivouak Sunglasses feature a photochromic lens that automatically adjusts its tint to the light conditions in each of these environments. It's also the first pair of mountaineering sunglasses to feature side shields that affix magnetically for easy adjustments with gloves.
