AMAZING - LOVE THESE!
Color: Blue, Size: Queen (U.S. Standard), Set name: Stretchy and Soft
I've been using these pillow cases for more than 6 months and LOVE them. They are well made, no wrinkling, fraying or wearing out, even with a weekly washing. I love the zippers on them, my pillows fits perfectly in the case and don't constantly escape from the case overnight. They definitely perform as described: they keep me cool at night and don't smell and actually don't make a mess of my hair. I bought an extra one and put it on a pillow I keep close to my body which helps me from overheating during the night. They are a great value for the price, I wish I could get top sheets in the same style as these and I'd be in heaven!

Cool Pillowcases
Color: Gray, Size: Queen (U.S. Standard), Set name: Stretchy and Soft
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.
