Our goal was to create a featherbed cover that was durable enough to withstand nightly "tossing and turning," as well as repeated hot water washings. We acheived our goal and added the luxurious element of touch. Our protector is woven and constructed in Germany from a 220 thread count white-on-white damask stripe fabric that has as fine a "hand" as many of the luxury linens that we've seen from Italy. Generously oversized to allow for shrinkage. Nylon zipper.
