Featuring icebreaker's best-selling 100% merino wool jersey fabric that’s breathable and naturally odour resistant, this top also features flatlock seams throughout to help reduce friction. 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.
