Questions people ask about merino
What is merino wool, and what makes it different from regular wool?
Merino wool comes from Merino sheep and is measured in microns — the thickness of a single fibre. Merino.tech uses 17.5 micron Australian merino, which is roughly a third the thickness of the coarse wool most people remember from old jumpers. Finer fibres bend against the skin instead of pressing into it, which is why merino feels soft rather than scratchy while still insulating, breathing and resisting odour naturally.
Is merino wool itchy?
No. Itch is caused by fibre diameter, not by wool itself. Fibres above roughly 22 microns are stiff enough to trigger the prickle response; ours measure 17.5 microns, well under that threshold. Every piece here is 100% Australian merino with no synthetic blend in the body fabric, so there is nothing rough sitting against your skin.
How do I wash merino wool without ruining it?
Turn the garment inside out, machine wash cold on a gentle cycle with like colours, and use a mild or wool-specific detergent. Lay it flat to dry. Never use fabric softener or bleach — softener coats the fibre and destroys the breathability you paid for. Merino resists odour, so you can wear it several times between washes, which is the easiest way to make it last.
What weight should I choose for a base layer set?
250 GSM is the answer for most people — it carries from the first frost through midwinter and works while moving or sitting still. Choose 165 if you run hot or plan high-output activity, and 320 if you are outdoors in deep cold without much movement. A set gives you the matched top and bottom in one weight, which is simpler than mixing.
Does merino wool shrink?
It can, but only under heat and agitation. Hot water and a tumble dryer cause the scales on the fibre to lock together permanently. Cold water, a gentle cycle and flat drying prevent it entirely. Follow that and the garment keeps its shape for years.
Can you wear merino wool in summer?
Yes, and it is one of the reasons people switch. Merino moves moisture vapour away from the skin before it turns into sweat, so a lightweight 165 or 180 layer runs cooler than cotton in heat. It also blocks UV — our lightweight fabrics carry a UPF rating of 25, the midweight and heavyweight options 50+.
