Pillow Wear(TM) Pillow Protectors are a second skin for your Canadian Down & Feather Company pillow. They provide an added layer of protection without compromising the luxurious feel and performance of your natural-fill pillow. This product has been carefully sized to fit your CDFC pillow like a glove after washing. The cotton fabric is 255 thread count, single-ply, featherproof twill weave, which makes for a durable, yet breathable material that can stand up to many washes. The 255 thread count version has a crisp, starchy feel and is recommended for pillows containing feather, including Down Perfect(TM) pillows. Pillow Wear(TM) features small side vents for air to pass through, which means that your pillow can puff, fluff, squish, sink, and breathe normally. These openings also allow your pillow's coloured brand label to be pulled through, so your pillow can be easily identified even with the protector on. Pillow Wear(TM) is finished with a double-stitched edge and a hidden zipper closure. As Pillow Wear(TM) is made only of cotton, it is not impermeable to moisture, pests, allergens, or bacteria. It provides some extra protection, but is designed as a light underlayer that allows your high-performance pillow to shine. This product is packaged sustainably with recyclable, biodegradable and water-soluble materials.
