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.
