The Merino 150 Anatomica Tank is a slim-fit and stretchy base layer top for daily pursuits and active weekend adventures. This top is made with a blend of soft merino wool and Corespun that is breathable and delivers all day comfort. Inspired by nature, icebreaker harnesses the performance qualities of natural fibres to offer an alternative to clothing based on petrochemical synthetics. Merino wool is an annually renewable fibre 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.
