Women's Merino Wool Base Layer Sets

Women's Merino Wool Thermals & Base Layer Sets

Thermal clothing for ladies has a reputation for being either warm or comfortable, rarely both. Merino solves that: at 17.5 micron the fibre bends against the skin instead of pricking it, so a womens thermal set can be worn under a dress, under ski kit or on its own around the house. Each set pairs a matched top and bottom in one weight.

What thermal wear actually does

Merino wool thermals work differently from the thermal underwear most people grew up with. Wool thermal clothing regulates in both directions rather than only trapping heat, so women's thermal wear made from merino stays comfortable walking from a freezing street into a heated office. Moisture leaves as vapour before it becomes sweat, and the fibre keeps insulating even when damp.

The range covers merino wool thermal tops, thermal layers for women, full thermal sets and separates. Wool thermal underwear in merino also resists odour, so a thermal set goes several days between washes.

Which weight

• 165 GSM — lightweight base layer women reach for in mild winters and high-output days.
• 200 GSM — the everyday weight for commuting, the freezing office, the school run.
• 250 GSM — the most popular thermal base layer women buy: autumn frost through midwinter, skiing and hiking.
• 320 GSM — heavyweight thermal sets for women in deep cold with little movement.

Why a set rather than separates

Buying a merino wool base layer women's set in a single weight means the top and bottom insulate equally — no cold gap at the waist, no overheating on top. Thermal sets ladies buy as separates often end up mismatched in weight, which is exactly what creates cold spots.

Care

Inside out, cold gentle wash, mild detergent, dry flat. Heat is the only thing that shrinks merino.
