A viscose undergarment is an article of clothing worn next to the skin, typically as a layer of insulation or for moisture management, that is made from a type of fabric known as viscose. Viscose is a type of rayon, which is a semi-synthetic fabric made from cellulose fibers derived from wood pulp. Viscose fabric is soft, absorbent, and has a draping quality similar to natural fibers such as cotton or silk, making it a popular choice for undergarments and other clothing items that come in contact with the skin.
