A furled leader (also known as twined leader) is a type of knotless tapered fly fishing leader. It is known for high performance, low memory,[1][2] and soft artificial fly presentation when casting. These attributes are due to the way these leaders are constructed which is similar to creating rope. The big difference is that furled leaders are created with a taper. The twisted style of construction and being made from many filaments leads to a flexible leader with low to no memory like a section of rope.
