Since they come as a set, i always have a clean one to swap out every 3 or 4 nights. Have gifted these pillows about three times already. Should replace pillows at least annually.

Each side of them is very different in terms if temp. This type of fabric is typically cooler and that's nice.

These pillow cases stay cooler than most of the others i have tried. My husband loves a cold pillow and these stay cold so nicely it’s sooo amazing. Very comfortable and pillowcase does stay cool.

The fabric stretches and it fit the pillow very snug. Comes with two silky pillow cases.

The pillow stays cool for about 30 seconds and then heats up. The pilings are only on the cooling side, the cotton side is fine!
