These are nice sheets. I bough the queen size.I would say that the weight is about average, not too thin, but certainly not heavy flannel. They are definitely warm - I cannot say how the pile will hold up in the long run. I consider them a good price.They definitely fit a thick mattress, which had been my concern in getting them.I bought two standard shams with the sheet set. The pillow cases that come with the sheets are simple, the ones that are standard shams have a border of material as you can see in the picture.
