These 100% wool underpants are perfect for those who don't like the tightness of tights or the rough feel of tights catching on their hands. These underpants and socks are a comfortable combination.

Wool is a natural, highly functional material that keeps you warm when it's cold and quickly absorbs and releases sweat when you sweat, making it comfortable to wear in both winter and summer.

It has a crisp, smooth feel and is free of the prickly irritation that is common with wool. It is gentle on sensitive skin that is prone to dryness in winter.

Since underwear is something you wear every day, it's essential that you can care for it at home. It has been treated so that it won't felt or shrink even when washed in water, so you can hand wash it with a mild detergent.

It's knee-length, reaching down to the calf. The silhouette doesn't cling too closely to the skin, trapping air between the skin and the fabric for warmth. It's comfortable without being too tight. It's thin, so it won't feel bulky even when worn with slim-fitting pants. Ecru is useful because it's not see-through, even when paired with white winter bottoms or overalls.

We also have No. 21 long sleeves made from the same material.
