Our covers feature an exclusive Zipper System, designed to fully encase your pillow. Recommended by Doctors. Keep your pillows clean and protected with the Two-Part System. The auto locking zipper ensures that it will stay closed. An added barrier creates a fabric shield under the zipper closure to doubly ensure there are no gaps. Our 100% cotton weave, is recommended by Doctors nationwide. Our fabric is woven so tightly that only air can get through. With a mean pore size of 2.6 microns, our breathable fabric keeps you cool, comfortable, and protected. Our pillow encasement is soft to the touch and noiseless when moving around while asleep. This pillow cover is designed to provide an extra layer of quality protection. Our cotton zippered pillow encasements are machine washable, making them a perfect choice. Our pillow protectors are easy to clean & use. Review: Have used for years all over our home - Throw pillow protectors are hard to find. 100% cotton throw pillow protectors are nigh impossible. We need them to keep the down feathers from poking through and more importantly to alleviate allergies and asthma triggers. We use these National Allergy Premium 100% Cotton encasements on all our bed pillows, mattresses and comforters. They’re brilliant. These are NOT INTENDED TO BE WATERPROOF. The tight weave will actually give you some stain protection and extra time to grab a towel if someone spills, but they are not intended to keep pillows dry. Pure cotton, smooth, crisp, work flawlessly for our allergen purposes. Workmanship and zippers are quality. I buy one size smaller than my throw pillow for hotel-like plumpness (20x20 protector on 22x22 down pillow and 20x20 case). But you may want to buy the actual matching size if your insert is very firm or very full. Tips: I always wash before use to soften and remove any smells or dust from manufacturing. To avoid shrinkage and wrinkles — wash in warm on delicate, dry on low temp and take out ever so slightly damp, smooth with your hands, and finish drying on a rack (or over a chair). They wash beautifully like this, no ironing. Yes, they are definitely more expensive than the 100% polyester, polyurethane-lined versions. But they last forever with reasonable care (don’t overstuff or yank on the zippers 😊). And your pillows won’t shrinkwrap into pancakes, fill up like balloons, crinkle like plastic grocery bags or fire up like heating pads under your head. Try both types (like I have) — unless you need water resistance, betting you’ll choose the all-cotton. Review: Pillow protector for throw pillows - Exactly as described. A perfect size for my 20x20 throw pillows. Would buy again. ## Features - Advanced Protection: National Allergy Euro Square Pillow Protectors are made from 100% breathable cotton, which promotes a sounder nights rest.

A perfect size for my 20x20 throw pillows.
