The body material is a twill fabric of the tune using a 1260D thread that has been twisted with Torayo "Farro®" as a vertical. Farillo® is a hollow nylon material with a unique luster and texture due to the special hollow structure. It is a material that is thicker than 20% lighter than the same 1260D, but has a moderate firm firmness. The finish is applied for water -repellent. The bottom is a three -layer fabric using Hollofil AirTM (66 nylon hollow thread) of Cordura® Brand Fabric, which is a highly durable and high -water -resistant original fabric. The attached suede is tanned with chromium, which is thick in North America, and then buffed carefully with sandpaper to make brushed finely. Because the thickness is a solid leather, the dyeing process is divided into two times, and the waterproofing is enhanced by adding a waterproof agent during dyeing. The leather arranged on the handle, etc., is tanned with 100% tannins, making it a solid leather that can enjoy aging. This series is a brand logo with an eyelet and an eyelet with a military -like daisy chain that combines high strength and high water -repellent material.
