Nice but dissapointing
So it sometimes stays cool but if it’s under a blanket and you have your body on it at all it will get warm but the spots you don’t use will get cool sometimes. I am very disappointed in the material though because it’s like my dry skin scratched the pillow case all over which makes me question it and I don’t think I would buy again.

Cooling fabric is Just what I needed
Color: 03-black, Size: 20" X 26" (Pack of 4)
I'm a hot sleeper. These cooling pillow cases are fantastic. It has ended soaked pillow cases. I paired these with waterproof pillow cases for extra pillow protection. I now sleep cooler and wake up dry. I also toss and turn less and wake up less frequently hot, sweaty and uncomfortable and I can sleep though the night. I don't need to flip my pillows over because of sweat. Both sides of these pillow cases have arc chill cooling fabric. They're soft, silky, breathable and comfortable to lay my head on. The colors to choose from is a wide selection. These look great on my king size bed. I love this fabric so much that I upgraded all of my pillows and blanket sheets to cooling fabric. I'm sold on these. The zipper is premium, sturdy and durable. My pillows fit perfectly on these cases. The cooling material is top notch high quality to me with great craftsmanship. I liked these ones so much that I bought more and plan to again. My partner seen and felt these and immediately went online to buy some blankets to go with the pillow cases I gifted. I also bought my son these and a few cooling blankets. These work best with a fan or air conditioner. Highly recommended and you won't regret this purchase if you're a hot sleeper to profusely sweating during sleep.

Color is off, feels decent
Color: 07-beige, Size: 20" X 26" (Pack of 2)
Feels nice and very cooling to the touch. Although you can tell it definitely isn't cotton. I ordered the color beige but it is much more of a cream color.
