These pillow cases are great for my hair and skin. They look good, hold up well in the washer and dryer, and the price is great. They are cooling. Of course I wish they could be more cooling, but honestly I'm not sure that's even possible. Great pillow cases. Already bought more for other heads. Would buy again.

Hot hot hot. Side sleepers will hate it

At first touch, these are the coldest pillowcases I own … but only for seconds. Once you actually lay on them, within seconds they adjust to your body temp, the heat feels trapped, my head begins to feel hotter than before I laid down - which has in turn caused me loathe these pillow cases. I hate that I have missed the return window. Would never buy again, would never recommend. My satin ones aren’t even this hot! I gave them the good ole 30-day try. Side sleepers - if you are like me and sleep on your side with arm tucked under pillow - flipping this pillow over in hopes of a cold side - forget it, it’s already hot from your arm.

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.

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.
