Scientific Anglers is credited with being the first fly line manufacturer to break from the tradition of braided silk lines by introducing something truly revolutionary: polymer coated fly lines. No longer did anglers have to treat lines to make them float, or dry them after a day on the water. Scientific Angler’s lines float higher, last longer, and require very little maintenance. Our proprietary manufacturing method allowed us to infinitely adjust tapers, to create lines tailor made for different environments and a variety applications. Scientific Anglers chose to use flexible PVC because of it’s incredible wear and bending strength and weather-ability. That’s how we make the most durable fly lines in the world.
