I absolutely love these LUXEAR pillowcase They feel cool and soft and they really help keep my pillow fresh and comfortable throughout the night.

Not worth it
Color: Gray, Size: King (20" X 36")
These start out nice and cool but within minutes your body heat turns them warm. Not worth the money.

Great cooling effect!
Color: Stretch Blue, Size: Queen (20" X 30")
I love these pillow cases! They are the best cooling pillowcases I have found. They do still eventually absorb the body heat and need to be flipped over but so far, the cooling effect of these cases outlasts the rest. I have had them for 5 years now and will not use any other cases. They are smooth like silk so I think they are good for my hair as well. The color is pretty close to what is shown in the picture and they fit most standard pillows.

Excellent pillow case
Color: Gray, Size: Standard (20" X 26"), Color: Gray, Size: Standard (20" X 26")
I bought this Luxear from pillowcase a few days ago and I’m very happy with it. The standard size fits my pillows perfectly, and the gray color looks modern and goes well with my bedding . I love it because It has two sides: one with cooling fabric that really feels fresh to the touch (perfect for hot nights), and the other side made of soft cotton, which feels cozy and comfortable. After just a few days of use, I already notice the difference. I sleep much more comfortably and no longer wake up feeling too warm. The material feels high quality and durable. It doesn't have any strange smell which I love from the first moment Definitely a great purchase!
