Avera Products Doormats Our outdoor entryway mats are made of all-natural, biodegradable and sustainable coconut fiber and backed with non-slip vinyl for durability and safety. The wide variety of unique designs are hand finished using permanent dyes for long-lasting style. Our heavy-duty doormats are ideal for high-traffic areas, including front entryways. While the natural coir material works great at absorbing water from your shoes, we strongly recommend keeping your Avera Products doormat in a covered area, away from the risk of being drenched in water - either from the rain or sprinklers/garden watering. Mats may discolor if soaked in water. Direct prolonged contact with the sun may result in fading over time.
