Lightweight polycotton poplin. Lining has been removed. No pockets. There are a couple tiny spots on the back as shown in the photo and a raised element to the knit at the bottom right. It's not a hole and may just be an imperfection in the poplin from factory I'm not sure.

Elastic is still very stretchy.
