The Merino 150 Anatomica Short Sleeve Crewe is a slim-fit and stretchy base layer top for daily comfort and active pursuits. The ultralight 150gm corespun fabric features merino fibres wrapped around a nylon core, for a top that is soft next to your skin. 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 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.
