I've been searching for cooling pillowcases for a long time. None ever seemed to fit the bill until I found these. Now, let's be clear, they are cool to sleep on for a good amount of time, but you will have to flip them occasionally throughout the night to keep getting that cold feeling. All in all, as a person whose face runs hot when I sleep, these cases have made my nights more bearable, and I do believe they are helping with my skin issues. As far as good value for the money, I think they are a little costly. Color was comparable to the online photo.
