Extra-large to provide maximum coverage, Nautical Flag combines contemporary flair with durability and purpose. This refreshing monogrammed look is made of coir, a renewable durable fiber that scrapes shoe bottoms clean and has a resilient vinyl backing that helps prevent movement. Coir doormats are all-seasonal, and they retain their shape. For best results keep in a sheltered area such as a covered porch, keeping extreme moisture and sunlight to a minimum. Vacuum, sweep, or lightly hose clean.
