Merino wool explained: why it works even in warm weather

Merino wool comes from merino sheep, whose fibres are much finer than ordinary wool, so it feels soft rather than itchy. It handles moisture well, resists odour and stays comfortable across a wide range of temperatures, which is why a fine merino knit works in air-conditioned offices and on cool Accra evenings without feeling heavy.

How fine is merino?

Wool fibre is measured in microns (thousandths of a millimetre). Merino used for clothing is typically under about 24 microns, and very fine merino under about 18.5 microns. Coarser wool is what makes traditional jumpers itch (Merino on Wikipedia).

Is merino too warm for Ghana?

Thick merino jumpers are. Fine-gauge merino knits and tees are surprisingly comfortable indoors and in the evening because the fibre handles moisture. Under the midday sun, choose cotton or linen instead. See knitwear in a hot country.

What merino pieces are most useful?

• A fine merino crewneck for the office
• A merino quarter-zip for travel. See how to wear a quarter-zip.
• Merino socks, which stay fresher in hot shoes. See what socks to wear.

How do I wash merino?

Cold or cool water on a wool cycle, or by hand with wool wash, then dry flat in the shade. Airing it overnight often removes odour without washing. See how to wash and store knitwear.

Does merino pill?

All fine wool can pill where it rubs, under the arms and at the sides. A knit comb removes pills. Higher-quality, longer-fibre merino pills less.
