I got these sheets because we needed some extra sheets for cold weather time. There's nothing worse than climbing into bed on a cold night into cold sheets. These are warm and soft on your skin. I have another pair of flannel sheets and they are really scratchy. These are also pre-shrunk so there's no risk of them shrinking after washing them.
These sheets also keep you warm, but I never got overly hot and sweaty. I think they do a pretty good job of helping regulate body temperature in the bed.
I am really glad we found such a great set of sheets. We will make good use of these.
