The main body material is a twill material that has a firm feel by densely weaving nylon thread with a warp thread of 70d and a weft thread of 210d. This nylon twill is treated with an original water-repellent finish, m-coatTM, which has far superior water repellency and abrasion resistance compared to conventional finishes. m-coatTM uses advanced special coating technology to structure the water repellent agent on the fiber surface, achieving excellent water repellency and durability. Many water-repellent products lose their water-repellent performance with repeated use and washing, but m-coatTM has obtained Bundesmann water repellency test grade 4 even after 100 washes. Regarding water repellency performance, we conduct the Bundesmann test (*), which is more severe than the spray test (JIS -L1092) used in conventional measurement standards. The accessory material is made of high-quality domestic leather, and during dyeing, 3M's waterproof material "SCOTCHGARD®" is included in the dyeing process, and the finish is made so that the waterproof material blends into the entire product, resulting in a highly waterproof effect. , and has a long-lasting effect. The leather surface is made with dyes and pigments to give it a transparent yet natural tone and atmosphere, and then a water repellent is sprayed on the surface to make it even more waterproof. This is a waterproof, stain-proof, and oil-proof leather that has passed the "SCOTCHGARD®" monitoring test. Both the main body material and the attached leather are water resistant, and this is a casual series that can be used in unisex fashion with metal parts. *The Bundesmann test is a quasi-practical test method for general clothing products, including waterproof fabrics, against rainfall.Compared to the spray test (JIS-L1092), the Bundesmann test is a method for testing general clothing products, including waterproof fabrics, against rainfall. The test lasts longer than 9 minutes.
