Rio

No matter what line family, price level or quality RIO fly line you choose, you can fish happy in the knowledge that every single fly line is made in Idaho Falls facility. There are many steps to making a premium quality fly line: drying out the core material, mixing the main coating ingredients, applying the coating to the core, curing the raw fly lines, coiling lines into individual coils, welding loops on the ends and so on. Of course, each line undergoes numerous quality control checks throughout several stages of manufacturing, as well as intensive product testing in the lab and on the water.
