White cotton jersey pillow protector with a thin waterproof polyurethane layer and zipper fastening. As the protector is 100% waterproof, it protects the pillow from liquids and moisture, while its high level of breathability allows air through. Machine washable up to 40ºC. The protector comes in a cotton jersey bag, the same fabric as the protector. This allows for easy transport and storage. All sizes are sold individually.
