The main body material is the original CORDURA Ballistic fabric, which uses 66 nylon thread of 1000D for the warp thread and 840D for the weft thread.

The warp yarn is made of 500D bright yarn, which is processed with ATY processing (using a machine to incorporate air into the yarn itself) to create a spun-like look, and then the two twisted yarns are pulled together, and the weft yarn is made of 420D bright yarn. The fabric is made of two twisted strands aligned together and woven into an oxford weave, making it a very durable fabric. In addition, by using threads with different standards for both length and width, the fabric has a deep depth with just the right amount of luster. The attached leather is made from high-quality steer leather from North America, and is tanned with vegetable tannin, which is gentle on the environment and the human body, without the use of chemicals or harmful substances that cause environmental pollution. The factory's unique dyeing and fatliquing processing technology gives it a soft feel while still giving it elasticity, firmness to the touch, and transparency. The finishing touch is an oil glazing finish that is done by hand by a craftsman, and by checking the condition of the finish, we further apply felt buffing to give the leather the best touch.
