The material known as "Tasmanian Tiger TARPAULIN 1000" is a fabric from the company "Tasmanian Tiger," which is a blend of two materials: 50% Polyester and 50% Polyvinyl chloride. It is a robust tarpaulin type fabric made from relatively heavy fiber (with a thickness of 1000 DEN) yet has a pleasantly smooth surface. It is primarily used by Tasmanian Tiger for backpacks. Additionally, its polyester surface is coated on both sides, making it easy to clean and completely water-resistant.
