How to measure

Measure yourself rather than a garment. Use a flexible tape measure over underwear or close-fitting clothing, keeping it level and snug but not tight. If you fall between two sizes, order the larger.

Bust - Measure around the fullest part of your bust while wearing your usual bra.
Waist - Measure around your natural waistline, the narrowest point.
Hips - Measure around the fullest part of your hips and bottom, with your feet together.

Superfine Merino Thermal Knee Length Leggings

The measure of merino

The softness of merino wool comes down to the fineness of its fibres. That fineness is measured in microns one thousandth of a millimetre. The lower the micron count, the finer and softer the fibre. Standard wool typically measures between 30 and 40 microns. By contrast, merino measures between 15 and 24 microns.

Coarser fibres are rigid enough to prick the skin rather than bend against it, causing an itchy sensation. Finer fibres, like merino, are soft enough to flex on contact, so they sit gently against the skin without irritation.

Within merino, there's even more variation. Our superfine merino sits between 17 and 18.5 microns. It's exceptionally soft and well suited to everyday wear. Our ultrafine merino measures below 17 microns. It's rarer, more expensive and closer in feel to cashmere.

Not ours. The prickle people associate with wool comes from coarse fibres — the thicker the fibre, the more it irritates the skin. Our superfine Merino is 18 microns and our ultrafine is 16.9 microns, both comfortably below the threshold at which most people feel any prickle at all. The result is a fabric that feels soft next to the skin, which is why our Merino base layers suit people with sensitive skin. If wool has bothered you in the past, it was almost certainly a far coarser fibre than this.

It comes down to what you want the layer to do.

Silk is the lightest option and close to invisible under clothing. It adds genuine thermal warmth without any bulk, which makes it ideal under work clothes, under a shirt, or for travel. Choose silk when you want warmth nobody can see.

Merino is the warmest and most hard-wearing. Our superfine and ultrafine Merino sits between 16.9 and 18 microns, so it feels soft rather than scratchy, and it's naturally odour-resistant and machine washable. It's the right choice for hiking, genuinely cold days, and everyday wear.

Bamboo is soft, stretchy and breathable, and it's our most affordable range. It's better suited to everyday comfort and sleepwear than to serious warmth.

Our wool is sourced from New Zealand farms committed to ethical animal welfare and sustainable land management. Merino wool is a natural, renewable, and biodegradable fibre.
