Cooling and comfortable against your skin
Color: Navy Blue, Size: 1 Pack Body(20x54)-Regular
Fits perfectly and feels nice against your skin. Just wish it had a zipper on the end. That would have made it perfect.

I am stunned
Color: Black, Size: Queen(20x30)
I had no idea what to expect from these. But for as cheap as they were I was willing to just write it off of they weren't that good.
I had already picked up a new memory foam pillow to replace my previous memory foam pillow that didn't do well with dissipating heat. This new pillow was fine by itself, but when I put my pillowcase on it, the properties that made it cooling were negated. I'd get a bit of sweat on the side of my head or my neck where it was against the pillow all night. The pillow was supposed to be a cool one, but the pillowcase was not.
So I grabbed this set. Smooth, no loose threads anywhere, stitching and seams are all spot on. And it's smooth to the touch. Got it on the pillow, and as soon as I laid my head down on it, I could tell immediately that this was going to be a different result that my other one. Not nearly as warm even after laying on it for a while. No heat buildup, no bits of moisture on the skin after being on it all night.
This definitely works well, especially with my cool sleep pillow. Now I can have a far more comfortable nights sleep. For the price, it's a steal. I have no idea what longevity will be, but with two of them, I'm sure I'll get more than my money's worth.

Soft and cooling
Color: Dark Grey, Size: 2 Pack Queen(20x30)-Regular
Soft, not too thick and wash very well. Feels great against my skin and doesn’t make my hair frizzy. Color was perfect.
