This car cover is naturally moisture resistant to acid rain, industrial pollutant, tree sap, bird droppings and more, and will not harm the fabric. It is breathable and dries quickly because the air can easily circulate thru the materials. This cover is easy to use because it doesn’t shrink as it retains its shape and comes with a 3 year limited warranty!
