This is an adidas CLIMAWARM. The size is 120. It was only used for sports during one winter, and has been worn about 5-6 times. The "a" in adidas has come off during washing. Also, there is some staining on part of the right sleeve. It might be removable with a stain remover like Uta-maro soap, but it will be given as is. For those who don't mind. It seems like it could be used instead of Heattech, and would be useful for skiing and winter sports ☆ It's made of thick Heattech-like fabric, so it seems like it would be fine worn on its own or layered.
