Love them

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%

Actually feels cool at night
Color: Light Gray, Size: Standard
I’ve been using these for several days now and I did notice a difference. I tend to get hot while sleeping, so I was curious if they would actually help, and they do feel cool when you lay on them. I also like that they’re soft and comfortable, not that weird texture some “cooling” products have. So far, I’ve been really happy with them.
