Super-Dri is the first flyline to take advantage of a wave of new nano-engineered hydrophobic materials. The guys at Airflo like to think of it as super-teflon. I prefer to think of it as super-awesome. Originally Airflo designed the Super-Dri lines to take advantage of the water repulsion properties of the new material and make the line float higher. What they didn’t anticipate was the legion of other benefits. The amount of line you can pick up and mend is unreal. The lines don’t just repel water—they repel dirt and scum as well. The lines feel slick all day, even in the grimiest of water.
