Hmmmm not really a cooling case
Color: 07-beige, Size: 20" X 36" (Pack of 2)
I bought these because like many I get hot at night, right around my neck. While it's soft and satin to the touch, and cool to touch, it doors keep me cool presay. I still get hot, I flip the pillow and because it's cool, I get cooled down. Again doesn't actually keep me cool all night though.

They are cool and that’s exactly what I wanted. Something that wasn’t hot and I’m very happy with my purchase.

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.
