The boldest expression of Carrera’s unique aesthetic – these unisex sunglasses from the Flag Lab collection push the boundaries of contemporary eyewear design. Sculpted from lightweight metal into a large navigator shape, the oversized full-rim front is enhanced by a layered construction for added depth and dimension. The unmistakable logo detailing rounds off this truly modern, statement-making pair. The Flag Lab gets inspiration by the utmost iconic and recognizable details of Carrera, with the Glory II leveraging on the stylistic elements of its sister best seller style Glory, offering a style for a stronger look. Notice the iconic Flag stripe in total black— the brand's trademark motif inspired by Carrera's ski-jumping 'Bullet' helmet — along the top bar as well as sleek metal temples which evoke the iconic Carrera Champion style, remastered in a luxurious modern way. Unconventional and always one step ahead.
