Fly fishing leader by rio is some of our best fly fishing leader we have. When you pair this with our fly fishin tippet, you have a great fly fishing set up.Leaders and tippet, though expendable, are vital pieces of equipment for any fly fisher. Without a solid leader and tippet setup, you run the risk of spooking fish or breaking them off. An appropriate leader means better accuracy, turnover, and presentation. The correct tippet selection ensures it will sink (or float) and be nearly invisible to the fish.
