Rio : Mainstream Saltwater, Blue, WF9F

MAINSTREAM SALTWATER: RIO's Mainstream saltwater fly lines have been developed to meet the overall needs of the average and novice fly fisher, and are designed to optimize rod performance with slightly heavier and shorter head lengths.

FLY LINE FEATURES: Every Mainstream line undergoes the same rigorous production processes and quality control standards as all RIO fly lines, and is made in RIO's Idaho manufacturing facility. Each saltwater line is built with a hard, saltwater coating for the best in performance. Targeted to the overall needs of the average fly fisher.

TECHNOLOGIES: RIO’s DirectCore is a low-stretch core used in tropical lines, that stretches 30% less than other tropical cores, exceptionally easy to pull coils out of, and lies perfectly straight on the water, while SlickCast creates the slickest, most durable coating on the market, producing the least amount of friction ever measured on a fly line.

SALTWATER FLY LINES: We offer a wide selection of saltwater fly lines for anglers of all abilities in all conditions. Whether fishing flats for Bonefish, Permit or Tarpon in the tropics or heaving big baitfish patterns into the surf for Stripers, we have the right line. A wide selection of both tropical and cold water fly lines ensure that we have every fishing condition and season covered. All fly lines are built with sophisticated tapers and the latest technology for the modern angler.

PASSION & INNOVATION: 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.
