The outer material is very scratchy, it’s fine if your planning to use an addition pillow case over it. The inside is like a rubbery plastic type material. I’m not exactly sure how I feel about it on my pillows though because the zippers are lodged and I can’t get it open enough to put a pillow in it. If you’re looking for something that will really protect from water or other stuff, these would probably be fine. They just feel more in line with something a shelter or an Airbnb would use rather than something to use at home for your personal pillows.
