Sweatshirt fabric made by using Pima cotton and elastic spun yarn. The surface thread uses ultra-long staple Pima cotton, while the backing thread features elastic spun yarn. The combination of high-quality raw materials and vintage machinery results in a fabric that boasts both a unique thinness and elasticity. It has a light yet rich texture. After sewing, the fabric undergoes garment dyeing to create a deep, worn-in color, as if it has been used for years. Ink Black Colorway.
