Merino wool base layers: Natural warmth and breathability
A merino wool base layer is one of the most versatile tops in any outdoor wardrobe. Merino wool is a natural fibre that breathes, regulates body temperature, and provides warmth even when damp. It is also naturally antibacterial and resistant to odour, making it a reliable choice for multi-day treks or ski tours. The Fjällräven women's collection of merino wool base layers includes both 100% merino wool and blends, giving you the flexibility to choose between different functionalities. Soft against the skin and lightweight to wear, these shirts combine comfort and performance in equal measure.
How to layer women’s base layer shirts for cold weather
Start with a base layer women's shirt as your foundation. Then add a fleece or lightweight insulated mid-layer to lock in warmth, and finish with a shell jacket for wind and weather protection. This three-layer system helps maintain your body temperature, keeps sweat under control, and ensures comfort across changing conditions.
Thermal base layer, women’s styles, for everyday comfort and extreme-cold performance
Base layer clothing for women isn’t only for outdoor adventures. Fjällräven base layers are designed to transition seamlessly between outdoor activity and everyday life. They double as cosy tops for relaxing at home, or work equally well under everyday jackets during cold commutes.
For the harshest winter conditions, thermal clothing for extreme cold is essential. The Fjällräven range of women’s base layers are crafted to provide maximum insulation while remaining breathable enough to prevent cooling sweat, whether you are climbing, ski touring, or spending long days outdoors. The fits, fabrics, and flat seams deliver freedom of movement and comfort all day long.
