Merino wool thermal underwear is one of the best purchases for autumn and winter! Merino base layer enables you to wear the clothes you love in chilly weather, and will definitely keep you warm in tough conditions. After all, the product has been tested in Finland!

Natural materials are good for sensitive and even atopic skin being breathable and comfortable. Wool absorbs moisture without feeling wet. Therefore it is an excellent material for activewear and underwear, etc.

The pants are high-waisted without a side seam. Designed to fit persons with long torso as well! The mens' merino underwear are double-layered on the front panel.

These measures are taken of the pattern. The fabric is very flexible, so we recommend choosing even a size smaller than usual in case you want the clothing to be tighter and hugging.
