Named for the Japanese phonetic for expedition, the Tanken range is designed for working up a sweat in the great outdoors. Light and quick drying, the Tanken Tank Top features hardworking FlashDry™ technology that actively wicks away sweat from your skin as you move. Capped sleeves, a lower back hem and a wide crew neck also give it the added bonus of being good-looking enough to wear far away from dirt trails and forest paths.
