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.
