Built with a powerful butt section that turns over easily, RIO's leaders are some of the most popular in the industry for good reason. Built with a copolymer material that provides great knot strength and allows for a great presentation that's easy to cast and use for dry flies, streamers, and indicator rigs. Each leader has a hand-tied perfection loop in the butt end for fast rigging. Why we Like them: We've carried Rio leaders from the beginning of our gear shop and have trusted them to deliver our flies on rivers, lakes, and salt-water across North America. Rio delivers a quality product that is consistent, innovative, easy to use, and affordable.
