Everyday basics usually begin with cotton or synthetics, and Merino can still prickle when broader fibres sit directly on bare skin. Paire grades the wool to the garment instead: 16.5-micron Ultra-Fine Merino for next-to-skin tees, and 18.5-micron Superfine Merino for thermals, where the slightly stiffer fibre helps hold the loft insulation needs.
One fibre, graded to the garment: fine enough to disappear into a tee, or lofted enough to warm a thermal.
Micron is simply fibre diameter, but that small measurement decides drape, prickle and warmth. In wear, Merino regulates temperature, moves moisture as vapour and resists odour through repeated use, which is why it is the traveller's fibre: fewer washes and steady comfort as climates change, whether that is a carry-on week away or the daily commute.
Microns measure the diameter of each wool fibre. A lower number means a finer fibre: Ultra-Fine Merino is 16.5 microns for a smoother, lighter feel, while Superfine Merino is 18.5 microns for soft, practical thermal warmth.
Both lines use fine Merino fibres selected for next-to-skin softness, rather than the coarser feel associated with traditional wool. Skin sensitivity varies, so anyone with a known wool sensitivity may prefer to test the fabric first.
Merino wool helps retain warmth in the cold while releasing excess heat and moisture as the body warms. Choose Ultra-Fine Merino tees for lightweight everyday wear and refined layering, or Superfine Merino thermals as close-fitting base layers in colder conditions.
Fibre diameter drives both stiffness and how firmly a fibre end presses into skin. At 16.5 microns the fibres bend rather than prickle, which is what makes an Ultra-Fine tee comfortable worn on its own. At 18.5 the fibre is slightly stiffer, so the yarn holds more loft — more trapped air, more insulation — which is what a thermal layer needs. Same wool, different job.
Follow the care label on the individual garment. Wash cold on a wool or gentle cycle with wool-safe detergent, avoid bleach and fabric softener, then reshape and dry flat away from direct heat.
Merino wool naturally manages moisture and odour, helping garments feel fresher across repeated wear. Ultra-Fine tees offer an easy travel layer, while the thermals provide packable warmth without the weight of conventional winter layers.
Wear it more, wash it less. Merino resists odour naturally, and the fibre lasts longer for every wash it doesn't go through. Turn it inside out when it does go in, and separate dark from pale.
Wool or gentle cycle, below 30ºC. Sheep don't like hot water.
Using soap? Keep it mild and wool-specific. No bio or enzyme detergents — protease digests wool protein. No bleach, no fabric softener.
Dry flat in the shade, away from direct sunlight and away from heaters. No tumble drying or dry cleaning please.
If you're ironing, use a warm iron with steam while the fabric still holds a little moisture. Never press wool bone dry.
Rest it 24 hours before wearing it again — wool fibre recovers its crimp and its shape when it's given a day off, which is what keeps a tee from going baggy. To refresh it without washing, lay it flat for an hour, or hang it in the bathroom while you shower and let the steam drop the creases out.
Store clean, folded, in a breathable cotton bag or box. Never hang wool for long periods and never store it dirty — moth larvae feed on wool, and the traces of sweat and skin in an unwashed garment make it far more attractive to them. Cedar blocks or lavender sachets nearby rather than touching the wool. If you vacuum-pack, add a silica sachet to catch trapped moisture.
Light pilling is normal and it settles down after the first few wears. Comb it off rather than pulling.
