Shimano Mastiff, which is made entirely of abilities and is manufactured in Japan under strict quality control, provides anglers with consistency and dependability while also combining strength, durability, and smoothness to improve water performance. Designers developed NANOARMOR ® technology, nano-sized ridges across the outer surface of the line, to increase knot strength and endurance, preventing slip, and lowering the risk of line break. Mastiff’s area is completely smooth to the touch.
