YGK Nitlon DFC is 100% fluorocarbon, made clear and hard for maximum abrasion resistance, durability and invisibility underwater.
Fluorocarbon is far more dense than nylon, making for superior abrasion resistance, and has an index of refraction very close to that of water, making it ideal for use as a leader, or as a casting line straight to the lure or bait. Only Nitlon DFC is equally suitable for both main line and leader.
Nitlon DFC is by far the most popular freshwater leader in Australia, and is the 'standard of the industry' for bream and bass fishermen.
