Question: Are these soft or plastic.  Do they make noise when you move your head
Document: It fits well but noisy. Like a plastic bag. I guess it has to be that way if it's waterproof. I bought it for my son because he sweats on his head but he doesn't use it. He grabs another pillow. Defeats the whole purpose.
When I purchased this product I did not have false illusions, I was expecting some plastic noisy crinkly product, boy was I WRONG! This pillow cover makes no noise. As a matter of fact, you can hardly even tell it is on your pillow. I was really impressed. I will be ordering two more.
Works great, wonderful price and doesn't make noise when you lay on it. Just purchased 2 more of the queen.They do keep bedbugs out. I recently had a problem and there were no bugs on my pillows.
I am not sure if we have bedbugs, but after a trip to Jamaica, we feared that we might have brought them from one of our less than pristine accommodations. The item is well made. The fabric is sturdy and the zipper works well. In hind sight, I wish we had used such covers for the pillows, just to protect the pillow. I do not agree with some of the comments, which say that the cover makes noise when you turn your head, etc.
I couldn't keep these on. They sleep hot and just make too much noise. Made my down pillows less comfortable. Can't say anything about their ability to keep out dust mites or bedbugs.
The "fabric" looks and feels like tyvek. Curiously, it does not make crunchy noises when you put your head on it, though. I ordered four (mistake). One out of four has a faulty zipper.
This product works like a miracle. I purchased the bed sheet and pillow covers from the same company. I was searching for a bedsheet and pillow covers that help with dust mite allergies. I was afraid that the crakly noise wouldn't allow me to sleep. Luckily, I came across this product. It does not make any noise compared to similar products. Overall, great product and would highly recommend.
I've used several brands of allergy proof pillow protectors over the years. These are by far my favorite. They hold up well in the wash compared to other brands. I've had a couple for 2 years now, with no problems. They feel more like fabric and less "plastic-y" than other brands. They are more breathable and comfortable to sleep on, and they don't make your face feel sweaty. I highly recommend these based on price, quality, and effectiveness!
For some reason I thought that this product would be soft, like a pillow case but its not. It deflates when I put my head on it but it will do for its purpose.
There is no plastic smell or feel. It is soft, comfortable and the zipper closure is quality made. I am buying more.
Answer: They are very soft and not plastic. You completely forget they are even on your pillows!
