In 1990, Jim and Kitty Vincent founded RIO® in the mountains of Idaho on the idea that exceptional fly fishing products should be built by anglers for anglers. More than twenty years later, they're still in Idaho and driven by that same ethos.

Through all those years, RIO has demonstrated passion, innovation, and a pure love for the sport through its development of some of the industry's highest performance fly lines. And the great news is, they will continue to research, design, and refine their products to ensure they're your preferred line of choice for years to come.
