“I sweat a lot when sleeping. Even when the air conditioning is on, I still do. Probably because of weight and lifestyle. So all of my pillows and bed sheets need to be changed every week or else they would stink. I was surprised when I used this for a week. It doesn't get warm, Though I still sweat, I could feel that the pillow stays cool. Also, probably the intriguing part is that it doesn't smell. It's been a week and 3 days now and usually, ordinary pillows would release a stench by now but this does not. I don't know how it happens but I am very happy with it .”
