Subline is a heavy Co-Polymer cord, that is based on newest materials and technologies. It is not only very tough, it also is very soft and flies very good. Additional to that the Subline sinks very well. Available in 2 colors, sub green and sub brown. Every 1000m spool has a removable cord mark every 250m. With that the angler knows how much cord he has spooled on his reel.
