Review on Ultimate Protection for Your King Size Pillows with MZXcuin Waterproof Pillowcase Protectors - Set of 2 Zippered Pillow Covers by Marcia Estrella

I gave 4 stars for now as I've only had it a few months. My husband sweats a lot, every 6-8 weeks we bought new pillows. After buying these pillows I didn't have to buy new ones. I will update the review after 1 year. ***UPDATE/TWO YEARS LATER*** HIGHLY RECOMMEND! These covers have withstood a sweat shop. In fact, they worked so well that I've just ordered another set so I don't have to wait for them to air dry before I wash them again. Remember that you can machine wash but not tumble dry. They have an internal rubber lining that is destroyed by forced heat. In the washing machine I turn them inside out and use the hooks to hold them open so they dry easily. Open the end (see picture) to let the moisture dry out, as they keep the moisture inside when you're not thinking about it. It's a pain in the back to use and care for, but it's worth it considering the number of pillows I've had to buy each year.
