They are a bit noisy to my liking since I am a light sleeper but they work great for my husband he is a heavy sleeper and nothing bothers him lol.
They truly work keeping our pillows safe from drools and stains. If you are looking for luxurious, soft covers they are not it, be ready to spend at least 2 times more. For the price these are perfect and work well for us. I got it while it was on special for $8 but the price had gone up since. Would I buy it for $23? Nope
