I am a hot sleeper and am always on the hunt for bedding that can help me sleep a little cooler. I've tried different mattress pads, sheets, comforters and still end up sweaty in the middle of the night. I read that cotton percale sheets were good for this, and I have to say that I am very impressed with these sheets. When I received them there was a very strong odor so I washed these before I slept in them. The odor dissipated after washing so I was very happy about that. I had a great night of sleep! The sheets were soft and cool. I did get a little warm, but no where near my usual temperature, so that's a win for me! I will definitely be buying another set.
