I love the feel and comfort of silk clothes against my skin but I never thought about a silk pillowcase until I tried it.   It is so silky and smooth.  The nylon zipper is easy to use to enclose the pillow and a nice extra instead of a fold over at the top of the pillow case. I noticed right away how “cool” my pillow felt against my face. An extra benefit is your hair retains some smoothness and no static electricity after a night’s sleep.  Hand washable.
