Shimano Mastiff Fluorocarbon

Shimano Mastiff is 100% fluorocarbon and produced in Japan with strict quality control that offers anglers consistency and reliability while combining strength, durability, and smoothness to enhance performance on the water. While the surface of Mastiff is entirely smooth to the touch, engineers devised NANOARMOR® technology — nano-size ridges across the outer surface of the line — to enhance knot strength and toughness, preventing slippage and reducing the risk of line breakage.
