The soft and stretchy Merino 150 Siren Tank is a sleek, stylish and versatile layering piece for any day of the year. Soft and comfortable thanks to its naturally odour-resistant Merino Corespun fabric, the Siren features a scoop neck and slim, flattering fit for feminine style. Inspired by nature, icebreaker harnesses the performance qualities of natural fibres to offer an alternative to clothing based on petrochemical synthetics. Merino is an annually renewable fibre that naturally resists odours, keeps you cool when it’s hot and warm when it’s not, and lets your skin breathe for comfort all day, every day.
