The best line treatment available, improving the performance and longevity of your fly line.

Loon Line speed is positively the best line cleaner, conditioner, and UV block for fly lines. By cleaning, adding a slickness, filling in imperfections and protecting lines from the sun, Line Speed allows lines to cast farther and last longer. Unlike most line cleaners, Line Speed doesn’t leave a sticky, dirt gathering silicone fluid coating. Apply with Loon’s Line Cleaning Tool and let sit overnight.
