Wool?
Waterproof fabrics are usually natural or synthetic fabrics that are laminated to or coated in some sort of permanently waterproofing material, such as rubber, polyvinyl chloride (PVC), polyurethane (PU), silicone elastomer, and wax. Examples include the rubberised fabric used in Mackintosh jackets and inflatable boats.
So you can have an organic fabric with either a natural or synthetic coating to make it waterproof.
since when is fabric naturally occurring?
