It’s you’re a hot sleeper - hurry and buy this pillow case !
Color: 03 - White, Size: Queen(20x30)
If you’re a hot sleeper ! This is the pillow cover you want!!!! Don’t hesitate to buy. I love how it has the zipper to it so the pillow doesn’t come out. Appearance is beautiful. Softness is rate 11 out of 1-10z. May wrinkle after wash a bit but once place on the pillow wrinkles go away. Great for your hair because of the material great value for your money.

I’m obsessed with these pillow cases. They make such a difference and feel so soft and cool. I’ve bought them for every bed.

Not so Cooling
Color: 01 - Grey, Size: Queen(20x30)
This pillowcase does not do too much to keep you cool. When not in use, it's cool too the touch but after laying on it for about a minute, it is no longer cool. Also, the color was supposed to be gray but it looks almost white and not gray. The material is comfortable, but overall, this is more like a regular pillowcase, not a cooling one, as advertised (which is the whole reason I bought it).
Update: Seller reached out and refunded my order since I was unhappy with the purchase. Great customer service. Thank you!

Keeping, but they do make me hot.
Color: 02 - Blue, Size: Standard(20x26)
Very soft and cooling at first, but they do get hot during the night. So bad that my face sticks to the pillowcase.
