The soft and stretchy Siren Tank is a sleek, stylish and versatile layering piece for any day of the year. Incredibly durable and super soft thanks to its corespun merino blend fabric, the Siren features a scoop neck and slim, flattering fit for feminine style. Inspired by nature, icebreaker harnesses the performance qualities of natural fibers to offer an alternative to clothing based on petrochemical synthetics. Merino is an annually renewable fiber that naturally resists odors, keeps you cool when it’s hot and warm when it’s not, and lets your skin breathe for comfort all day, every day.
