They are usually natural or synthetic fabrics that are laminated to or coated with a waterproofing material such as rubber, polyvinyl chloride (PVC), polyurethane (PU), silicone elastomer, fluoropolymers, and wax.
What material is most waterproof?
Gore-Tex. The best in the industry and the most popular when it comes to waterproof fabric is most definitely Gore-Tex. It is a brand recognised across households across the globe, and it's because they are one of the first and top-performing waterproof fabric creators.
There are however naturally water-resistant materials like beeswax and lanolin that can be used to protect all kinds of fabrics like cotton jackets, leather shoes, canvas bags, tents and more!
