I wanted something that was more cooling than my cotton sheets since I tend to run hot. These were a little strange to get used to, I'm not sure why. They just felt...different. It took a night or two to adjust. They're comfortable, don't wrinkle, help keep me cooler, don't stain, etc... All you can really want in sheets. But we've had them for about a year now and they haven't stretched into a strange shape, pilled, or ripped. After all this time, they look like they did when new and I'm still happy with them.
