Crafted for those who pursue demanding, high speed activities, the Julbo Aero Zebra Sunglasses are uncompromising when it comes to performance and comfort. The photochromic Zebra lenses darken and lighten as ambient light conditions change to keep up with your varying surroundings, while offering a broad vision spectrum through their wide surface. Ensuring an unbeatable hold in all conditions, the 3D Fit Nose utilizes special wingtips for adjustability that matches every type of nose shape. Suspended lens construction with aeration delivers complete air circulation to prevent fog build up, and the Grip Tech inserts at the stems provide an exceptionally comfortable hold that doesn't get stuck to your hair. The Air Link temple system employs shock absorbing elastomer inserts at the end of the temples for more comfort and an even lighter weight.
