The main body fabric is made of nylon twill fabric that has been specially processed.
The warp thread is 210D and the weft thread is 420D, and the fabric is specially processed to shrink the fabric, making it denser and more resilient. The included leather is chrome tanned and dyed, then finished with pigment, and then embossed with square grain to increase the strength of the surface and give it an elegant look. By applying color to the embossed uneven top, the shadows are clear and a sense of depth is expressed.
