The Always Cool Pillow (Soft Density).

"Effective under any pillowcase, this is the pillow that actively regulates your head's and face's temperature, creating an optimal sleeping climate by preventing overheating. It uses a fabric developed for NASA to help astronauts adapt to extreme temperature fluctuations. It absorbs excess heat from you when you are hot, ensuring a comfortable pillow temperature every time you use it. The fabric covers both sides of the pillow, which is filled with a spiral-crimped polyester that has a loose, thread-like texture that provides long-lasting loft. It is encased by a 300 thread-count hypoallergenic removable, washable 100% cotton cover. For those who sleep on their stomachs. Soft Density King. 36"" L x 20"" W. (5 1/4 lbs.)"
