RIO Dacron Fly Line Backing - Filler Spools

RIO's traditional Dacron braided backing features high strength and low stretch and is unsurpassed in quality.

• Good compromise between thinness and the ability to make blind splice loops
• Easier to knot than very thin backing with an overly tight weave

Choose from 20 lb and 30 lb strengths in the available filler spool sizes and colors.
