keeps pillow secured and cool
Color: 05-purple, Size: 20" X 26" (Pack of 4)
just what I was looking for. A cooling pillow case with a zipper! my regular pillow cases slipped off my pillows So annoying. Now my pillows are staying put zipped in. so soft and cool. no more wrestling with the pillow case while trying to flip my pillow over trying to find a cool spot.

Color is off, feels decent
Color: 07-beige, Size: 20" X 26" (Pack of 2)
Feels nice and very cooling to the touch. Although you can tell it definitely isn't cotton. I ordered the color beige but it is much more of a cream color.

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.
