Icebreaker Men's 200 Oasis 1/2 Zip Long Sleeve Top

The benchmark against which all others are judged, the 200 Oasis Long Sleeve Half Zip is icebreaker's best-selling base layer—a versatile active top for year-round layering and everyday comfort. Made with soft, breathable, and odor-resistant 100% merino jersey fabric, the Oasis also features a classic zip-neck design for easy layering and quick temperature regulation. Underarm gussets and set-in sleeves add mobility, and offset shoulder seams and flatlock stitching prevent chafing. Inspired by nature, icebreaker harnesses the performance qualities of natural fibers to offer an alternative to clothing based on petrochemical synthetics. Merino is an annually renewable fiber 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.
