A down body pillow is an investment to protect, and this pillow protector does the trick at keeping off sweat and body oils. Measuring 20 by 54 inches, the lightweight protector is made of 100-percent cotton in a tightly woven 200-thread count. A very slight nap adds softness. A white zipper runs across one of the narrow ends, adding contrast to the protector if it's in one of the available non-white colors. The pillow protector can be machine washed with like colors and tumbled dry.
