Ugly
Color: 01 - Light Grey
The light blue color looks like a hospital gown. Keeps cool but I don't think I can bear looking at it.

Cooling pillowcase
Color: 01 - Light Grey
These cooling pillowcases are fabulous. I just have one complaint they snap at the end instead of having a zipper, which could be uncomfortable if you’re laying on that snap. Also, it’s very hard to unfasten.
