I bought this pillow for my son because he is a very hot sleeper. He said he really likes this pillow because it gets really cool when he’s not touching it and doesn’t get as warm as his other n  pillows.  His only complaint is that it’s a little more full or fluffy than he’s used to so it’s taken a bit of adjustment on the thickness of the pillow. Other than that, he says it helps keep him a little cooler at night.  He likes it!
