Review on 🌙 Ultimate Comfort Guaranteed: CALM NITE Pillow Protector 2 Pack - Extra Soft Knit - Waterproof Zippered Case for King Size Pillows by Wendy Owens

Excellent Pillow Cover - You can see how it protects the pillow from moisture/liquids. You can see this in action when you wash them and put them in the dryer (it is not recommended to tumble dry at too high a temperature as the special material could potentially melt or stick to itself). I didn't realize I was buying something like this but they ended up on my husband's pillows and even my own as sometimes I can go to bed with my hair not completely dry. I will be buying extras as we have a beach house and the air is humid so I'm really glad I stumbled across them. You can see that they are made of quality materials. I've had something similar before and melted them in the dryer (I don't always read the fine print!). I highly recommend them. If you want to see what they do, wash them and then try drying them. You will need to partially open the loop and fold it inside out to dry the inside. All I can say is great technique!
