The Muscle Tank is our take on a classic design, with a relaxed fit silhouette. Wear it to your next gym class over one of our bra or crop tops. Cut from our new MicroFlex technical fabric that feels super soft, weightless and luxurious all at once. Soft to the touch, it will absorb and wick way sweat, so you can focus on your goals. Made of a lightweight blend of micro-nylon and spandex.
