My husband has been sleeping very hot lately, so I decided to look around for some cooling sheets. So many of the reviews of these said that they were amazing, that they stop night sweats, that they are so cool and wonderful! We did not find that to be the case. The crisp cotton sheets that we usually use feel way cooler than these, and stay cooler throughout the night. These just feel like polyester sheets. Disappointing, but at least they weren’t very expensive.
