Thin yet warm thanks to moisture absorbing heat generating material and brushed finish on the skin side

The smooth and soft fabric makes it very comfortable to wear. It absorbs moisture and generates heat, so you will feel warm when you wear it.

Since it has no seams, it's not only comfortable and warm, but it also doesn't show under your outerwear, making it very useful.

It's thin but very warm. I'm looking forward to wearing it in the coming season when I commute by bicycle.

The fluffy cotton blend brushed material provides warmth even on cold days.

It's warm because it's fleece lined. Also, it has no seams so you can wear it with any clothes.

It's warm and comfortable. I used to fight the terrible static electricity every winter, but this underwear doesn't generate static electricity, so it's very comfortable to wear.

It's warm the moment you put it on. But it's not too hot and it's very comfortable to wear. For those living in the north, it's great for the coldest season, but it's also great to wear under a thin layer of clothing around this time of year.
