Sherpa fleece is a type of fabric made from polyester. It is a variant of stretch knit polyester fleece fabric. It has two distinct sides; one has a smooth knit side, and the other side has a texture intended to imitate the look and feel of a real sheep's fleece.
Sherpa fleece is primarily used as a jacket lining or in pet beds. Polyester fleece fabrics are lightweight yet warm. They are soft, water-resistant and easy to work with. They come in a variety of different finishes including the Sherpa fleece finish. The most common type of polyester fleece finish is called a brushed finish.
