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.

Light, soft, and packable, you'll reach for this breathable, lightweight tank top again and again for active pursuits or just cozying up on the couch.
