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.

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.
