Icebreaker Women's 200 Oasis Base Layer Thermal Top, Black

The 200 Oasis Long Sleeve Half Zip is an ultra-comfortable base layer top that makes the perfect foundation for cold-weather layering. Featuring Icebreaker's best-selling 100% Merino Wool jersey fabric that’s breathable, insulating, and odour-resistant, the Oasis also features a classic zip-neck design for quick temperature regulation. Underarm gussets and set-in sleeves add mobility, while offset shoulder seams and flatlock stitching prevent chafing. 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.
