Bull Denim Fabric is a natural pre-shrunk 100% cotton fabric.  It is a tightly woven, heavyweight upholstery fabric.   It is a 3×1 twill weave, allowing for superior strength and hold. Alongside its lasting durability and stiffness, it is a flexible fabric that is soft to touch. Compared to the common denim fabric which is made from dyed warp and weft thread, the bull denim is made with un-dyed warp and weft thread.
