For more than 20 years, RIO has demonstrated passion, innovation and a pure love for the sport through its development of the industry's highest performance fly lines. And the great news is, we will continue to research, design and refine our products to ensure they are your preferred line of choice for years to come.

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, we're still in Idaho and driven by that same ethos.
