Ready-Fit Car Covers are actually a semi-custom universal car cover. They are designed to provide a very good fit using incremental sizing, but is not custom made per vehicle. The Covercraft Technalon Evolution Series covers are a tan colored 4 layer polypropylene constructed car cover made for maximum protection in all outdoor weather conditions! This U.S. made fabric is natuarally 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. The middle two layers of the Evolution fabric act as a filtration barrier versus most airborne pollutants as small as 0.1 microns! The Technolan Evolution car cover has Impact Absorbtion. The think 4 layer cover absorbs impacts to help prevent your vehicle’s paint from dings, dents, and scratches. This cover is easy to use because it doesn’t shrink as it retains its shape and comes with a 4 year limited warranty!
