The Icebreaker Merino 200 ZoneKnit Long Sleeve Crewe is a performance base layer designed for active use in cold conditions. Made from 100% merino wool with an 18.9-micron fibre diameter, the fabric naturally helps regulate body temperature and resist odour build-up.

ZoneKnit™ technology uses strategically engineered knit zones to help release excess heat during intense activity. Eyelet mesh panels provide additional ventilation where it is needed most.

Raglan sleeves and underarm gussets improve freedom of movement and comfort. Flatlock seams help reduce friction, while integrated thumb loops keep the sleeves in place and provide extra wrist coverage. The drop-tail hem offers additional coverage during movement.

Its slim, close-to-body fit makes this top ideal as a first layer under additional clothing.
