This technology used to build th NV4 utilizes a unique fiber processing system that blends two premium nylon types in the fiber cabling process. Chosen for their special properties, this exclusive formula yields greater stability, life, and balance throughout the entire body of the rope. The blended nylon fibers are then fused with high tensity poly for enhanced action and speed. A patented Coretech™ center provides increased loop stability and tip weight. Yet the outer diameter is smaller, making it faster and easier to control. The NV4 has a snappy, responsive feel for greater confidence and highly visible catches.
