Levi's 503 + Mad Barbarians. The Crazy Concept is based on Mad & Pop! Whatever that is! MAD is apparently indicative of blood splattered anarchy which is combined with print and embroidery of the character POP, which we're informed is a crazy, ironic and idiosyncratically Eastern mix. The jeans have a coin case, specially made bag, can batch, sticker and post card. Levi's 503 + Mad Barbarians jeans are limited to an amazing 250 pairs! Worst of all they're only available in Taiwan!
