He usually doesn't pay much attention to these close-fitting clothes. Just put them on, but I still think that close-fitting clothes must be comfortable enough, so I bought my boyfriend a tree with a little carbon black to let him feel it. He is really more comfortable than the long-sleeved clothes he used to wear, and it is very light and comfortable to wear. He can wear small carbon black and play football with his colleagues.

We usually have the configuration of thermal underwear+down coat+cotton-padded jacket. We usually don't feel cold when we go out, so we can put on down jackets after a while.
