I’ve been using these for several days now and I did notice a difference. I tend to get hot while sleeping, so I was curious if they would actually help, and they do feel cool when you lay on them. I also like that they’re soft and comfortable, not that weird texture some “cooling” products have. So far, I’ve been really happy with them.

I highly recommend this pillow case. With two sides it is easy to stay comfortable as the weather changes. The cooling side is nicely cool to touch and both sides are incredibly soft. The size is also good.
