R18 is Seaguar Japan’s premier fluorocarbon mainline with top-of-the-line overall performance. It delivers excellent performance in three key areas: strength, suppleness, and castability.
This line was created with Seaguar’s exclusive double-structure process with two custom Seaguar 100% fluorocarbon resins to create a line with exceptional knot and tensile strength.
It’s soft, supple and very manageable - easy casting and very smooth coming off your reel.
They are offered on 100-meter spools which is 109 yards.
