Built for mountain biking, the Julbo Blast Zebra Antifog Photochromic Sunglasses excel in mountain environments. Their Photochromic lenses will adjust when your bright afternoon ride morphs into a low-light evening pedal. Designed to be worn with a helmet, you can count on a good fit with your brain bucket, while an anti-fog coating will keep your field of vision clear when you're hitting V02 max on the ascent. And when the ride is done, you can sport these puppies around town while you check out what the local brewery has to offer.
