We bought these sheets because they are supposed to stay on better with our vertex mattress protector. Our salesman when we bought our bed Convinced us that we needed the protector and new pillows. Anyways, the sheets are soft, but they do nothing to help convey coolness. I still wake up hot. They also stay on our bed better than our old sheets. So that's a plus. I don't think any of it is worth the money we spent on it.
