This item was produced in 2024. Due to rising raw material costs, we have revised the price and made it one size larger. The size is larger than the size 38 of the product produced in 2023. Customers who purchased last year's product should note the difference in length. The material has not changed, but the ecru has become a slightly creamier color.

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. Wearing these underpants and socks together will keep you comfortable.

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

It has a crisp, dry 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.
