Woven with multiple Japanese Dyneema fibers, the strongest in the world, this is one tough braid.

No frills and completely frictionless, this super-soft 4-strand superline allows for long distance casts with no tip whip on spinning and centerpin rods.  

In 50LB and 65lb, it makes the perfect trolling backing line for copper and lead core setups minimizing wind drag when used with planer boards.
