Rio Fly Line Backing

RIO's traditional Dacron® braided backing features high strength and low stretch, making it unsurpassed in quality. This backing is a perfect compromise between thinness and the ability to make blind splice loops. Unlike other brands that are very thin but have a too tight weave for a blind splice loop, RIO's Dacron backing is easier to knot. It is a high-quality and super smooth braid that is 100% reliable.
