Kingnex Feather Proof Pillow Protectors with Zipper Standard Size 2 Pack - 100% Waterproof - Down Proof - Terry SurfaceThe premium pillow protector comes economically packaged in a flat vacuum wrapped plastic bag. Inside the bag there are two pillow protectors, something that I hadn't noticed in the ad, but a very welcoming site to find. The exterior of the pillow protector is a soft to the touch almost terrycloth pattern fabric. The protector itself is a lot thinner than I thought. It might be. The inside of the protector is billed as being waterproof and featherproof. It looks like it has a plastic liner of some type. But it doesn't feel plastic to the touch. There's no washing instructions on the pillowcase itself, but on the cardboard insert in the package it recommends that you do not dry clean, machine wash cold, do not bleach, do not iron, tumble dry low, and do not use softener. (Why not softener?) I bought these pillow protectors because I have a feather pillow that I've had for many years. That is very comfortable except for one thing. As it's gotten older, the pins of the feathers tend to work out of the pillowcase and get past the pillow cover and end up scratching me. Not comfortable, and indeed annoying. I'm hoping that this pillow protector will help with that issue.After sleeping with the new cover in place under my regular pillow cover and over the bare pillow itself, I can say that it works well. No scratchy pin feathers sticking out last night!
