Rio Mainstream Trout Type 3 Sinking Fly LIne

by Rio

    RIO's Mainstream series of 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. 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 line is built with a slick coating on a supple memory-free core, for the best in performance. 

  • Slightly heavier than standard lines for easy loading
  • Supple core with a slick coldwater coating 


For more than 20 years now, RIO has delivered on their promise for passion and innovation in fly fishing, with a pure love of the sport and some of the industry’s highest performance fly lines. Originally founded in the mountains of Idaho in 1990, they continue to research, design and refine their products so that they remain your go-to choice of line for many years to come.

With welded loops, extreme slickness and supreme versatility just being a few of the inherent qualities within RIO’s range of Gold, Perception and Scandi Short fly lines, the pay-off of literally thousands of hours spent on the water is allowing you the pleasure of throwing the highest performance fly lines around.
