Furled leaders are made of polyester and offer unbeatable suppleness, no memory and excellent energy transfer.
Treated with a long-lasting water repellent, just dry the leader after use and place it back in the package and it should remain floating after many uses.
To use, just add 2 to 3 feet of tippet to the tippet ring, then attach your fly to your tippet. Longer tippet sections can be built out by adding a small section (1-2 feet) of material a
size heavier than the final tippet section.
