These sheets are very soft and very lightweight which allows them to breathe. I did feel like I was sleeping cooler with these sheets on my bed. The big downside, and why they only get three stars, is that they don't fit my bed (LUXEbreeze) well. Within a short time they are all bunched up and don't fit tightly on the mattress at all. If the fit were better these sheets would get a better rating. So, I would recommend these sheets with the caveat that they do bunch up a lot.
