Love!
Color: Blue, Size: Queen (U.S. Standard), Set name: Stretchy and Soft
Awesome cases! They really are cool to the touch. I didn’t sleep hot at all. I have a “cut-out” memory foam pillow, and this stretched around it perfectly. It is flexible enough that it doesn’t impede with the cut out. And while the material is “silky,” it doesn’t slide around the pillow while sleeping on it. The zipper feature is perfect. I washed and dried per the tag instructions and they washed very well. Super happy.

AMAZING - LOVE THESE!
Color: Blue, Size: Queen (U.S. Standard), Set name: Stretchy and Soft
I've been using these pillow cases for more than 6 months and LOVE them. They are well made, no wrinkling, fraying or wearing out, even with a weekly washing. I love the zippers on them, my pillows fits perfectly in the case and don't constantly escape from the case overnight. They definitely perform as described: they keep me cool at night and don't smell and actually don't make a mess of my hair. I bought an extra one and put it on a pillow I keep close to my body which helps me from overheating during the night. They are a great value for the price, I wish I could get top sheets in the same style as these and I'd be in heaven!

Cool Pillowcases
Color: Gray, Size: Queen (U.S. Standard), Set name: Stretchy and Soft
These pillow cases are silky soft and cool to the touch. They don’t stay as cool as I would like, however, so I find myself moving around on the pillow to find a cool spot or flipping the pillow over. I have washed them several times and the coolness seems to be diminishing. Still, it’s better than a regular cotton pillow case. The zipper is needed and helps keep the material on the pillow.

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.
