A 100% fluorocarbon monofilament fishing line designed to be used as tippet material, especially when using saltwater techniques. Fluorocarbon has a low refraction index and is virtually invisible in water. Contrary to nylon, fluorocarbon is waterproof, which means that it doesn’t lose resistance even after a long time in the water. Since the specific weight of fluorocarbon is heavier than water the line sinks.
