I love these satiny pillow covers. They protect my pillows and make it really easy to put on my regular pillow cases. I have purchased other types of these in the past that do not have zippers on them. I am so happy that these do. Since I use them under the pillow case,the zipper keeps them nicely in place.
These can't possibly be anti-microbial. These are the thinnest pillow protectors I have ever purchased and I have purchased many for our vacation rentals. I would not recommend these to anyone. It seemed like a good value, but the poor quality makes these worthless and a waste of money.
These were a bit thin and I'm not sure would protect the pillows from stains. I bought them mostly to keep feathers in a feather pillow so they definitely server that purpose. If you are looking for something that is highly protective, I'd go with a higher priced, higher quality item.
I was expecting the fabric to be more tightly woven on the pillow protectors I purchased. My pillows are down and I don't think the weave is going to keep the down feathers from escaping. I put two protectors on each pillow so price wasn't so good.
