Louis Vuitton by Tyler Nano Porte Documents Voyage Bag. This XS version of the Porte Documents Voyage business bag, the Nano Porte Documents Voyage city bag, is made from Damier Golf canvas with pale cowhide-leather trim. Fruit of the collaboration between Louis Vuitton and Tyler, this golf-green version of the Damier checkerboard pattern is perfectly offset by Tyler’s flower-shaped Louis Vuitton charm.
