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 smooth cover

Color: Grey, Size: Body（20"X 54"）

This is a nice pillow cover overall. The fabric feels good and it's comfortable to sleep on, especially compared to a more basic cotton cover. It is maybe a little thinner than I expected, so if you want something thick and heavy this probably isn't that. But for a soft smooth cover that fits and feels decent, I think it's worth it. No major complaints from me after using it.
