Material: is very stretchy and cools well. It has a zipper which is good because the fabric is very soft and slippery and if it didn’t have a zipper the pillow would not stay in the case. Durability: zipper works great and material is easy to clean. Color: I have the gray and my daughter has the pink. Both colors as advertised. Value: Good value and I got what I expected.

Very soft and cool.

Color: Dark Gray, Size: Queen

Very comfortable and cooling. But after a couple of washes the stitching starts to unravel.

Actually feels cool at night

Color: Light Gray, Size: Standard

I’ve been using these for several days now and I did notice a difference. I tend to get hot while sleeping, so I was curious if they would actually help, and they do feel cool when you lay on them. I also like that they’re soft and comfortable, not that weird texture some “cooling” products have. So far, I’ve been really happy with them.
