Heavyweight merino half zip for women who want reliable warmth, breathability and everyday comfort from the mountains to town.
The Icebreaker Womens Merino 300 Original Long Sleeve Half Zip Top is a modern take on Icebreaker’s classic merino pullover, built from 100% merino wool in a warm 300-weight knit. The versatile half zip lets you fine-tune airflow on the move, while the natural merino fibres help regulate temperature, manage moisture and resist odour whether you are layering for winter missions, travelling, or wearing it day to day. A regular fit gives room for light layers underneath without feeling bulky, and the soft merino knit feels comfortable straight against the skin. Rib details at the collar, cuffs and hem add structure and durability for long-term wear.
| Waterproofing | Pure merino knit with no waterproof membrane or coating, designed as an insulating mid layer to be worn under a shell in wet conditions |
| Warmth | Heavyweight 300-weight merino fabric delivers substantial insulation and thermoregulation for cold climates and winter layering |
| Fit | Women’s regular fit that layers easily over a base layer and under a shell without excess bulk |
- 100% merino wool: Naturally breathable, odour resistant and temperature regulating for comfort across changing conditions.
- 300-weight knit: Heavyweight warmth ideal as a cold-weather mid layer or stand-alone pullover on crisp days.
- Half zip neck: Allows quick venting when you heat up and zips high for extra coverage when the temperature drops.
- Soft rib collar, cuffs and hem: Enhance durability and help seal in warmth while keeping the pullover sitting comfortably in place.
- Merino comfort feel: Luxurious hand-feel that works just as well for everyday wear as it does for travel and mountain use.
