Great case
Color: 03-dark Grey, Size: 20" X 26" (Pack of 2)
Love these pillow cases! FYI: 20" X 26" are PERFECT for supposed "queen size" feather pillows. 20" x 30" ones are too big and allow the feather pillow to flatten out too much. There is a bit of stretch to the cases. The "cool side" of the pillow case IS NOTICEABLY COOLER than the other side. Good zipper.

Hmmmm not really a cooling case
Color: 07-beige, Size: 20" X 36" (Pack of 2)
I bought these because like many I get hot at night, right around my neck. While it's soft and satin to the touch, and cool to touch, it doors keep me cool presay. I still get hot, I flip the pillow and because it's cool, I get cooled down. Again doesn't actually keep me cool all night though.

That I keep my head, cool
Color: 01-grey, Size: 20" X 26" (Pack of 2)
They are cool and that’s exactly what I wanted. Something that wasn’t hot and I’m very happy with my purchase.

super smooth, silky, stays comfortable feeling. DO NOT DRY or wash with heat
Color: Blue, Size: Queen (U.S. Standard), Set name: Stretchy and Soft, Color: Blue, Size: Queen (U.S. Standard), Set name: Stretchy and Soft
I'm impressed. I have used cooling pillow cases before, and found them effective, but the cooling material have always been on just one side. These are 100% cooling material. The material is super smooth and silky feeling. It is great feeling against hair and skin (even better than my old polyester satin I was using before cooling pillowcases). The material is cool, and does not seem to get hot hot. The pillow cases are super stretchy with a small hidden zipper. They grab onto the pillow and dont loosen up. Makes my pillow look neat and clean, not sloppy from loose material. I can even have two pillows stacked and somehow despite being a smooth material, the pillows dont just slide off each other.
The cooling aspect works by not trapping heat, not allowing heat to get to the pillow and hold it there. So yeh, the pillow case will feel warm eventually but if you have a fan, or AC, or flip the pillow, then it is is truly cool. Otherwise in my experience when I use a pillow without this, the pillow just gets hot, stays hot, and even with flipping it feels hot.. because the pillow itself has trapped the heat for remainder of night. Yuck.
One thing to know and this is very important-- as I learned the hard way-- DO NOT DRY IN DRYER. DO NOT WASH IN HOT WATER. Heat will destroy the material ability to feel and stay cool. Do you want a regular heat trapping pillow case? Then go ahead and dry these in the dryer a few times and you will have a regular pillow case. HOw do I know? I bought these to replace another set (different brand, same idea, same instructions that I failed to remember). I always dried them in the dryer, and one night after having gloriously cool pillows, I noticed that my pillow was HOT night after night. It was then when looking for another set of pillow cases that I learned that they cant be exposed to heat like that. SO PLEASE, just AIR DRY.
And so, after I got these and put them on my pillows, I had a much better nights rest. I remember thinking that I wasnt waking to rearrange my pillows. They were just comfortable all night long. Sure, I'd love an even colder pillow, but our room is on the warm side. But at least I wasnt noting the hot hot pillows anymore.
