This is not a sweatshirt type material. In person there is a sheen on this, and the fabric is like an exercise nylon. The photo shows no sheen on the fabric to indicate that it has a bathing suit nylon/spandex type sheen. It may be polyester, but it is not a sweatshirt type knit as shown in photo, it is a satiny finish, which is not explained in the description nor shown in the photo.
