It’s like sleeping on a beach in San Vito lo Capo
Italian voice:
I’m a big meaty fella so I put off a lot of heat ya hear. These pillow cases have changed my life. One moment they’re hot and the next you flip them and you’re blasted with a blast of ice cool what it feels like to chew 5 gum feeling capeesh. I would reccomend these pillow cases to even my grandma. If ya wanta get a rest so good that it feels like ya been sleeping with the fishes get these pillow cases, they’re the real deal. Then stop at Pauline’s joint and grab a slice of pizza say Vinnie sent ya. Anyways I gotta go my wife’s cooking up a mean lasgna and we’re gonna watch the dodgers. Let me know how these treat ya I guarantee they will change your life. Vinnie out

Soft "cooling" case.
Yes it is very cool when you lay on it. It doesn't stay cold though. Within a minute or 2 to whatever your temp is.

Great for hair and skin. Great buy.
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.
