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.
