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.

COOL Pillowcases Worth Buying

Color: Champagne, Size: Queen

I bought these to try out, and I was shocked to find they worked out better than my silk pillowcases. I have atopic dermatitis, and I need a pillowcase that doesn't irritate my skin. I also am having hot flashes and need something cool on my face. These pillowcases are perfect for both my conditions. I plan to buy more in different colors. My sons and husband also like it since they are always hot.
