The main body material is INVISTA’s CORDURA® and two 315d Hollofil AirTM (66 Nylon hollow fiber) fibers. A fabric that has passed the CORDURA® brand fabric standard has strength against abrasion, tearing, fraying, etc. The back surface is PU coated, and the special moisture-permeable waterproof film L-VENT® is laminated to further improve water resistance. This results in a 3-layer structure in which tricot nylon is also laminated. This master-piece original fabric “MASTERTEX-08TM” has durability, water resistance, and water repellency. The material used is high quality steer leather from North America. The leather is placed in a drum and then dye and oil are added to make the base. Waterproofing agent is sprayed at the finishing stage to further enhance the waterproofness. Waterproof, oilproof, and stainproof leather that has passed the 3M “SCOTCH GARD®” monitoring test. The test is performed by scraping the surface. The bottom surface is made of INVISTA’s 1680d CORDURA Ballistic® nylon, which has about 5 times the wear, tear strength and durability of normal nylon, and the back surface is PVC processed for further strength and waterproofing. In terms of functionality, the cushion of the shoulder harness uses Outlast®, a temperature control material developed for NASA, and the mesh material improved softer feel. The base of the front features tape woven with a slit fabric with a reflective function on the tape attached in a loop shape for safety at night.
