When I purchased this item it was called Cotton Duvet set. There was no indication of fabric content on the listing other than the title. When I received it I realized that it definitely wasn't cotton and, furthermore, there was no indication of the fabric content on the packaging or labels. It was too much hassle to complain and ship it back, but now I see that the listing is clearly stating that the set is polyester. Bad for me, good for those looking in the future. I do like the silvery gray color and washability. However, the snaps are cheap plastic and the stripes only run vertical if the snaps are located on the side.
