This durable square pillow cover set for 17-inch toss pillows is a great way to upgrade the look of your patio or decorative living room, den or bedroom pillows. They feature zipper closures and are designed to last because they are made from 200 gsm spun polyester. The 500-hour color fastness ensures the cover will last for many seasons. Please note that while the fabric is weather-resistant, we still recommend storing the pillows indoors or in a storage box when not in use to keep them vibrant and clean.
