Query: Heavy duty and good quality material

Got the cover for my new patio set. It fits perfect for a 54" table and 4 chairs. I can tie the cover to the table if it gets windy. Nice neutral color but it might show dirt after the rain. The material is almost water proof but if you let the water sits on it for a long time, it might get through to the furniture.
