Merino wool fabric
The very fine wool of merino sheep (about 15–24 microns). The fibre is much finer than ordinary wool, so the yarn is soft and doesn't itch.
How it feels
Soft, light, no itch.
Season: Autumn and winter – it keeps you warm.
What it's used for
Sweaters, base layers, socks, sportswear.
A fine merino sweater works under a blazer and for travel – it barely creases and stays fresh. For sport, it's the base layer under a shell.
Pros
- Regulates temperature – warm without overheating
- Stays fresh for days
Cons
- Pricier
- Shrinks and felts like any wool
Care: a typical label
Always follow your own garment's label – blends and finishes change the care.
How it's constructed
Knit. One yarn interlocked in loops – so the fabric stretches sideways and creases less, but can stretch out.
A little history
Merino sheep come from Spain, where exporting them was punishable by death until the 18th century. Most are now raised in Australia.
How to recognise it
Animal fibres feel warm and springy – they bounce back when crushed. They burn smelling of hair and leave brittle black ash.
Sustainability
Biodegradable and long-lasting. Animal welfare matters: look for RWS (wool), the Good Cashmere Standard, and non-mulesed labels.
When buying
Rub the knit – if it pills at once, the fibres are short. '100%' or a high share of the natural fibre is warmer than acrylic blends.
