The cover has been made from a heavy-duty 4-ply non-woven polypropylene fabric, which is highly water resistant, UV stable and breathable. The breathability of the cover is its most important feature – condensation can regularly occur underneath a vehicle cover, which can then lead to water sitting on the van for sustained periods and so damp or mould may occur – this cover has breathable properties to allow any water to evaporate out and hence eradicate any of the above possible issues.
