I am a hot sleeper. Prior to these buying these I had been using "SHEEX® Arctic Aire Tencel® Lyocell 300-Thread-Count Sheet Set" which I loved but wore through too quickly for the price. After two nights with these sheets I plan to keep them even though they don't have a cool to the touch feeling when I climb in. The material feels high quality, it has a linen material look, but doesn't feel that way, and I like the stripes.
Overall these sheets work for me knowing that I have AC and a fan to rely on if needed. If cooling or temperature regulation are your #1 concern, these may not be for you.
