If you're looking for the best fishing line that appears invisible to fish underwater, our fluorocarbon fishing line is the way to go. With options made of fluorocarbon or with a fluorocarbon treatment, our fishing line stands up to tough fish and environments and provides excellent knot strength. When you want fishing line with more stretch and buoyancy, choose a monofilament fishing line from our selection, offered in a variety of colors and spool capacities.
