Extremely cold, silky, gentle on hair
Color: White, Size: Queen
This was so cold when I removed it from the package that at first I thought it would be too cold. It was as if it had been in a freezer. I really like how silky it is on my face. (I can't stand a rough feeling pillowcase.) It is also gentle on my curly hair. The pillowcase can warm up from being slept on, but a shift of just a few inches gets back to wonderful cold. I highly recommend this as an extremely cool, silky smooth fabric. These are much colder than my very expensive miracle sheets.

Freaking Amazing 🤩
I never write reviews but these pillow cases absolutely deserve one!!! These are absolutely amazing! So soft and cool! I sweat so bad every night!! I wake up and my hair, shirt and pillow are drenched!!! I slipped these bad boys on as soon as they came in, and let me tell you! They were cold to the touch, I woke up this morning and I wasn’t sweating! I thought $20 something dollars was a little expensive for 2 pillow cases but was totally worth it! We love love love them!🩷🩷🩷Hubby approved😉

Stretchy Material and Cooling Fabric
Color: Light Gray, Size: Standard, Color: Light Gray, Size: Standard
Material: is very stretchy and cools well. It has a zipper which is good because the fabric is very soft and slippery and if it didn’t have a zipper the pillow would not stay in the case.
Durability: zipper works great and material is easy to clean.
Color: I have the gray and my daughter has the pink. Both colors as advertised.
Value: Good value and I got what I expected.

Very soft and cool.
Color: Dark Gray, Size: Queen
Very comfortable and cooling. But after a couple of washes the stitching starts to unravel.

I LOVE THESE PILLOW CASES. I love the zipper so it stays on the pillow, how it stays cool, and the fabric. Worth it 100%
