Merino silk base layer

A merino silk base layer gives a lighter, smoother feel than standard wool thermals. This silk winter underwear is designed for close-to-skin wear in cooler weather.

The blend combines merino wool with 25% silk. Merino supports temperature balance and moisture control, while silk adds softness and a finer touch. The result is especially comfortable under everyday clothing, ski wear or other winter layers.

Choose tops, leggings and matching sets for travel, outdoor use and long winter days. The fabric stays breathable and offers warmth without the dense feel of heavier thermal underwear.
