Your pillows are a valuable part of quality sleep. Although pillows can be washed, it's easier to wash a removable pillow cover. Pillow protectors keep your pillow cleaner longer, which can extend the life of your pillow. Pillow covers can protect your down pillows from wear & tear, moisture, dust mites, fluids and stains. They're easy to remove with a zip closure and can be machine washed & dried. A pillow cover is a small price to pay for peace of mind.
