The picture I linked is of a buckwheat pillow. Had no idea they were a thing before today.
What about silk or bamboo pillow cases?
I’ve only ever really used cotton pillow cases and cotton stuffed pillows. I recently upgraded to a foam pillow that I’m enjoying.
You’ll be even more disappointed when you find out that “Aloe Vera Microfiber” is indeed coated polyester, with a few percent of Aloe Vera extract:

Honestl, I’m equally disappointed - I was keen to learn about a previously unknown fiber.
