The Leggero deviates from our Classic aviator with straighter lines & and a more rectangular vintage shape, perfect for that 'cocaine dad' look. Traditional sunglasses break, fall off, hurt the sides of your head, and are difficult to store. By replacing the arms with a built-in cord, Ombraz (pronounced ohm-bruhz) don't break, won't fall off, and, when worn correctly, are surprisingly more comfortable than ordinary sunglasses. Ombraz are equipped with world-class Zeiss optics and a lifetime warranty. 'Ombra' means shade in Italian. We plant 20 mangrove trees for every pair sold. Through our tree-planting initiatives, each pair is 1,714X carbon-negative, making Ombraz the most carbon-negative product sold on the planet.
