The Icebreaker Merino 260 Oasis Long Sleeve Half Zip is a warm and comfortable base layer designed for cold-weather performance. Made from 100% merino wool with an 18.9-micron fibre diameter, the fabric feels soft against the skin, helps regulate body temperature and naturally resists odour build-up.

The high collar and half-zip opening allow you to adjust ventilation as conditions and activity levels change. Gusseted underarms provide improved mobility and comfort, while offset shoulder seams and flatlock seams help reduce friction during movement.

With its slim, close-to-body fit, this top works well as a first layer and can be comfortably worn under additional winter clothing.
