Love the feel of the sheet set but very disappointed in the cooling effect that your website describe. It is not at all cooling when sleeping. In fact tit gets really warm and still waking up sweating. This purchase was completely unsatisfied. I washed it so I have to keep it. I am very disappointed in this product.

negative
