Great case
Color: 03-dark Grey, Size: 20" X 26" (Pack of 2)
Love these pillow cases! FYI: 20" X 26" are PERFECT for supposed "queen size" feather pillows. 20" x 30" ones are too big and allow the feather pillow to flatten out too much. There is a bit of stretch to the cases. The "cool side" of the pillow case IS NOTICEABLY COOLER than the other side. Good zipper.

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.
