Absolutely love this. It has a button closure and ties inside the corners for the duvet insert. I washed and dried this to try to get the wrinkles out, but it might need to just lay on the bed for a while. We’ll see how this holds up in the next few months. The material is a little thinner than I expected. (UPDATE) I slept under this last night. I love warmhot weather and like to be warm while sleeping, no matter what the season, but this is really warm with the duvet insert, even with the AC turned on. I’ll have to sleep under this without the duvet. When winter comes, I’m sure I’ll be toasty.
