Named for the Japanese phonetic for expedition, the Tanken range is designed for working up a sweat in the great outdoors. Though the Tanken Polo also looks pretty good indoors, too. But just because it looks casual doesn't mean it isn't technical. Featuring quick-drying FlashDry™ technology, it actively wicks away sweat helping to keep you dry. It's light yet durable and has a tactile, textured feel.
