The Julbo Dust Sunglasses have a snug fit to hug your head whether you're mountain biking or outdoor racing. The slim design also slightly suspends the lenses for prime ventilation, and it lets you slip the flexible frame under your helmet with ease. Photochromic Zebra Light lenses get darker and lighter according to the light intensity around you. The lenses also have some give, thereby reducing the risk of shattering if you fall. Anti Fog and hydrophilic coatings resist condensation, markings, smudges, and water. Julbo added a Grip nose pad and Grip Tech temple pads to further prevent the risk of these sleek shades slipping off your face when you're ripping up the trails.
