Didn't even realize what a duvet cover was, ordered it thinking it was like a comforter. It's very thin, not much thicker than a sheet, with a zipper all across one end. Looked it up and found out you're supposed to insert a duvet (known as a comforter in US) into the duvet cover. However, since it's warm weather now, we're just using it as is. It is very soft and comfortable and it's growing on me!
