From the product's homepage: This is the popular "PORTER SMOKY" series, which combines high-tech and low-tech elements, using PORTER's original fabric to offer a total collection ranging from casual items to business and small accessories. The main material is an original CORDURA duck fabric woven with uneven yarn of Zimbabwean cotton for the warp and CORDURA nylon for the weft. This fabric has a unique texture unlike any other woven fabric, combining the natural look of cotton with the supple luster of nylon. Because it is woven with two materials with different characteristics, the dye is not uniform, resulting in a pale color. The deep "navy color" gives it an elegant and calm atmosphere. Thank you. Color: Navy系 (Navy-based) Accessories: None Stains/Tears: None
