I got this pillowcase for my husband because he is always hot at night and has trouble falling asleep because of it. The fabric of this pillowcase feels very similar to a cooling pillowcase that I have had for years and love (but is discontinued, so I can't get any more of them). It is a silky smooth, not-quite-satin fabric that feels initially very cool to the touch. It fits on a standard size pillowcase, and has a slight pocket end (not very much overlap, so it does come untucked during the night). My husband reports that this pillowcase is very cooling right when he goes to bed, but after a short while, it warms up and isn't really cool anymore. So if he doesn't fall asleep right away (and he usually doesn't), he has to flip it over. His head puts out a lot of heat at night though, so the pillowcase might stay cooler longer for others.

Doesn’t stay on the pillow.

Color: Gray, Size: Queen (2 Count)

The concept is there, but the pillow case doesn’t stay on. Every night the pillow case slides either half way or completely off the pillow. If it stayed on I would love it

Very comfortable and cooling. Love them. Help me fall asleep faster and stay asleep instead of flipping my pillow all night.
