Review on 2-Pack Cooling Pillow Cases – Standard Size, Double Sided Cold & Moisture Wicking Covers with Hidden Zipper – Japanese Cold Tech Pillowcase Protectors for Hot Sleepers and Night Sweats by Mayur Kreps

I bought these pillowcases because I am very satisfied with the duvet from the same company. These are very soft and smooth. The material is slippery, so the pillow tends to slide off when the head of the bed is raised. This isn't a problem if you're actually using a pillow. I like the zipper, it keeps the case in place well. The material feels cooler than a thicker cotton pillowcase. Don't expect miracles when it comes to cooling. The material seems to give off heat quickly, but it's not magic and it warms up where your head is. Overall, I like the feel of the material, the cool feeling when you move your head, and the flash.
