RIO Premier Fathom Clean Sweep Sinking Fly Line

Product Code

A unique sinking line available in two different sink rates, designed for the stillwater or reservoir angler.

Models Available: S2/S4/Int and S4/S6/Int

Sizes Available: WF5 - WF8

RIO’s CleanSweep lines are a series of sinking lines built with a clear intermediate front end, seamlessly attached to a faster sinking body section and then to a slower sinking running line. This blend of sink rates results in a deadly fly path through the water, with the line “sweeping” the depths during a retrieve—from the surface, to deep, and back to the surface again—covering a
multitude of depths with each cast. Each line has a short, quick-loading head for minimizing the number of false casts, and a Hang Marker that shows anglers when to stop stripping. Built with RIO's exceptionally slick, durable SlickCast coating.

  • The body sinks faster than the tip or running line resulting in a deadly “U” shaped retrieve
  • Clear 7ft intermediate front section
  • Short, quick-loading head for easy-casting and quick distance
  • Hang markers at 20ft shows where to fish “The Hang”
  • Welded loops and ID on each line for easy identification and quick changes
