I highly recommend these sheets. I would give them a 5++ if I could. These truly keep you nice and comfortable. Even if you do have a "hot flash" they cool down so quick that sleeping has improved quite a bit for me.
They are comfortable, however they do not stay on the bed good. Everyday we have put the fitted sheet on the mattress as it comes off. My suggestion is to maybe go a size bigger. If they fox the fitted sheet problem then a 5 star
We had nothing but trouble getting sheets to fit and stay on our bed. We went ahead and ordered a set of the GhostSheets and wished we had done it sooner. SPEND THE MONEY, you'll be glad you did.
