This is a second pair I have bought. They really do work and prevent pillows from being stained from moisture and they are not hot.
they are the best pillow protectors I have used
Comfortable pillow protectors
So far so good
These are excellent because they are not too thick and bulky making them easy to wash and dry. I have given them to my parents in-law who thought it would feel like sleeping on plastic but were surprised how comfortable they were and how their pillow is staying fresh and stain free.
