Women's thermals for hiking, skiing and everyday winter

A base layer that fits well and handles sweat is the foundation of a warm outfit. Here is how the range breaks down.

Tops for every temperature

Choose from crew necks, zip necks and turtlenecks across a range of weights. Shop all women's baselayer tops to compare lightweight layers for active days with warmer layers for the cold.

Leggings and bottoms

Icebreaker's high-rise merino leggings and Patagonia's Capilene Midweight bottoms sit comfortably under walking or ski trousers. See the full range of women's thermal leggings.

Merino or synthetic

Icebreaker 200 Oasis is a lightweight 100% merino layer and the 260 Tech is its warmer midweight version. Patagonia Capilene and Odlo Active Warm are synthetic layers that wick sweat and dry quickly, and Odlo adds odour control to help keep you fresh.

Frequently asked questions

What is the warmest women's base layer?

For the coldest days look at heavier weights such as Patagonia Capilene Thermal Weight, a microfleece layer, Odlo Active X-Warm, which adds double-layered insulation in key areas, or Icebreaker's 260 merino range.

Are merino base layers itchy?

Fine merino base layers are made to be worn next to the skin and feel soft rather than scratchy. Icebreaker and Smartwool both use fine merino jersey for their base layers.

What should I wear under ski trousers?

A pair of thermal leggings or baselayer bottoms. They keep your legs warm and dry and add little bulk under shell or insulated ski trousers.

How should a women's base layer fit?

Close to the skin without feeling restrictive. A snug fit lets the fabric move sweat away from your body, which keeps you warmer when you stop.
