The fabric is made of 20D ultra-thin cicada wing spun fabric and has undergone high-tech nano-triple protection treatment: waterproof, stain-resistant, and downproof; the fabric surface is smooth and dense, with a satin-like luster, a soft and smooth feel, and excellent wear resistance. It is also easy to wash and quick-drying, and has a certain anti-static effect. 2.
