The first of its kind in home textiles, the Washable Wool Filled Pillow Protector is a luxurious upgrade to our classic pillow protector. It’s crafted with a fully traceable wool blend that’s machine washable—an innovation that’s never been done before—and is temperature regulating, naturally hypoallergenic and unbelievably soft. This adds an extra layer of comfort to any pillow, while the Cloud Soft Organic Sateen cover offers a smooth, warm handfeel.
