Julbo Sunglasses Shield - Black, Brown Julbo has developed stylish glasses for versatile mountain athletes, taking into account their flexibility as well as their technical perfection. The SHIELD is the good companion in any terrain. It offers all-round protection and a huge field of vision with self-tinting REACTIV Photochromic lens for a good view at all times. And with its non-slip, curved temples and Grip Nose, it won't budge even in the most jarring conditions. Its Air Flow ventilation and removable, pleasantly soft, textile "Soft Shield" side panels guarantee maximum wearing comfort. In addition, it scores stylistically with its elegant rectangular shape.
