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.

Soft and good quality fabric

Color: Dark Gray, Size: Standard

I have senstive skin, so the feel of fabric is important to me. These pillowcases were nice and soft. The material had a nice weight to it and you could not see through the material. Came out of the wash well too, not wrinkled.

Very happy with these and they are as advertised. Very soft on the skin and have survived many washings. Quality made and very reasonably priced. Highly recommend.
