A versatile base layer shirt perfect for everyday comfort and year-round layering performance, the Merino 175 Everyday Long Sleeve Half Zip features 100% merino wool rib fabric that’s soft, breathable, and naturally odour-resistant. The stretchy slim fit provides easy-layering performance ideal for any active adventure, and the half-zip design allows for quick temperature regulation. 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.
