Merino is wool from the Merino sheep, prized for a fibre diameter far finer than ordinary wool. Extra-fine merino, worsted-spun into a smooth long-staple yarn, produces knitwear that is lightweight, wrinkle-resistant and comfortable next to the skin. It is the fibre behind the classic English fine-gauge knit and much of the world's best layering knitwear.
What makes merino wool luxury quality
- Micron count: extra-fine (under 18.5 µm) merino is soft enough for next-to-skin wear; coarser merino may itch.
- Spinning: worsted-spun merino is smoother and stronger than woollen-spun; look for long-staple fibre.
- Gauge: fine-gauge (24–30 gg) merino knits are a luxury speciality, requiring precise machinery and skilled linking.
- Treatment: superwash treatments make merino machine-washable but can flatten the hand; untreated merino keeps more bounce.
- Origin marks: certified Australian or New Zealand merino often carries traceability schemes.
Care
Hand-wash or gentle wool cycle in cool water; dry flat; store folded with cedar to deter moths. See the full care guide.

Merino wool: frequently asked questions
Is merino wool luxury?
Extra-fine merino, worsted-spun and knitted at a fine gauge by a specialist mill, is genuinely luxurious and often more practical than cashmere. Ordinary merino used in performance base layers is a commodity fibre. The difference lies in micron count, spinning quality and the mill's finishing.
Merino or cashmere: which is better?
Cashmere is softer and warmer for its weight; merino is more durable, more breathable and easier to care for. Many knitwear specialists offer both. For everyday wear and travel, extra-fine merino is often the better choice; for warmth and softness, cashmere.
