Review Content Keeps things cooler Before this purchase, I was always flipping my pillow a few time a night to get the cool side face up. I have not had to flip my pillow once since using this the last 2 weeks. It also washed up well and I did not notice any pilling or shrinkage..LOVE IT!!! Great addition for the temp pillow! Bought 2 of the temperature regulated pillows, then, we got the pillow cases as well. Cool Pillowcase Sleep on it every night and I love it. Temperature regulating pillow case Based on research from the Space Program, this pillow case is made from fabric which helps control body temp fluctuation. It is soft but not flimsy. It does not stay "cool" to touch but rather doesnt get "hot". For those of us with hot flashes or just warm sleepers, this makes it very comfortable and reduces perspiration significantly. Excellent product I loved the Pillow cases, they really do keep you cool ,,, Cooling Found With a "cool pillow" inserted into this pillowcase, I can always find a cool spot on the pillow. Helpful for menopausal women!! Worth every penny! I have slept better the first night using this and it came in the mail so quickly too! This is the website Im gonna start using to buy stuff since its so cheap! Great Pillow Case Got tired of flipping pillow over when it got too warm. Havent had to do this with this pillow case. pillow case doft and comfy Good product. So far so good....cant wait till Summer..
