RIO Grand Floating Fly Line zoom in


RIO Grand Floating Fly Line

RIO® Grand is a full line size heavier than the industry standard, and features more weight distributed towards the front of the line to easily load faster action fly rods. Built with a short head that is easy to cast, this line is also an excellent choice for novice casters who need a little more feel when casting. 

The folks at RIO have enhanced the performance of this wonderful trout line by building it with SlickCast™ - RIO's proprietary coating technology. SlickCast creates some of the slickest, most durable fly lines on the market. Lab tests show that lines built with SlickCast have the least amount of friction ever measured in a fly line. In addition, the line features MaxFloat™ Tip Technology, RIO's proprietary tip coating formula that floats more than twice as high as regular line tips, without any increase in diameter.

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.
