Mixed material of 88% polyester and 12% polyurethane Black, long-sleeved innerwear - Size: L (96-104) - Material: 88% polyester, 12% polyurethane - Color: Black *Brand is unknown ---- Thank you for viewing. I am selling an item that I purchased but have kept in storage with the tags still attached. You can check the material and details on the tags shown in the photos, so please take a look at the size and material. Since it is unused, I cannot tell you how warm it is, but I would be happy if someone could use it as a winter innerwear. Please purchase if you understand.
