There is a woman in your life — maybe it is you — who does not slow down. Lacing up trail runners before sunrise, catching flights with a carry-on and a plan, running half-marathons at the weekend and still making Monday morning look easy.

What she wears while doing it matters more than it sounds, and this is where merino earns its reputation.

Why merino wool suits women who move

Women tend to run cooler at the extremities and warmer at the core, with a narrower comfort band than men. That is exactly the situation merino handles well, because it adapts rather than picking a temperature and staying there.

Thermoregulation means the same layer warms you on a cold morning trail and sheds heat when the afternoon sun arrives. Moisture leaves as vapour instead of soaking the fabric, so there is none of the clammy feeling synthetics give. And after a ten-mile hike, the thing most people notice: it does not hold odour.

Every piece in the women's collection is 100% Australian merino at 17.5 micron — no blends, no synthetic content in the body fabric.

What to choose, by how she uses it

For the runner: merino t-shirt, 165 GSM

At 165 GSM this tee breathes better than anything else in the drawer on a warm run. The fibre sits soft against skin and moves moisture from the first mile. Pair it with 165 GSM pants for a complete lightweight kit.

For the traveller: long sleeve, 250 GSM

Pack one long sleeve, wear it four days straight, still feel fine on day five. The 250 weight handles a cold aircraft cabin and an evening walk in the same garment, and it comes out of a bag without creases.

For everyday: half-zip hoodie, 190 GSM

The piece that bridges outdoor performance and normal clothes. The 190 weight works in spring, autumn and most of the days in between, and the zip gives you a vent when you warm up.

For real cold: thermal set, 250 GSM

Our best-selling set, and for a simple reason: it is the base layer that makes every layer above it work better. Skiing, snowshoeing or walking the dog at 20°F — matched top and bottom means no cold gap at the waist.

Frequently asked questions

Is merino wool itchy for sensitive skin?

Not at this fineness. Prickle comes from fibre diameter, and anything under roughly 22 micron sits below the threshold. Ours measures 17.5.

What merino weight should a woman start with?

165 if you run hot or want one piece for travel and warm weather. 250 if you want one piece that carries autumn through winter. Most people end up owning both.

Can you wear merino for running?

Yes, and the odour resistance is the clearest benefit — a merino tee after a workout does not smell the way a synthetic one does.

How many days can you wear merino while travelling?

Three or more wears between washes is normal. Airing a garment overnight resets it, which is why one long sleeve covers most of a week.

How do you wash merino without shrinking it?

Cold water, gentle cycle, mild detergent, lay flat to dry. Heat is the only thing that shrinks it. Full method in our care guide.
