Scientific Anglers' Backing doesn't just connect your fly line to your reel, it also provides insurance for those drag-blistering runs of steelhead or bonefish. It works hard. Now let it look good. The Dacron backing offers a thin diameter, high abrasion resistance, and peace of mind, knowing that the fish of a lifetime won't be getting away from you this time. #desdes# Scientific Anglers fly line backing is extremely thin has a low coefficient of friction high abrasion resistance is colorfast and has high visibility. Fly line backing is what goes on your fly reel before the fly line itself. Usually 100 to 300 yards of backing is used but check with your fly reel manufacturer for the rmended amount specific to your fly reel.

The RIO Fly Line Backing is super high quality, just what you would expect from RIO. RIO’s traditional Dacron braided backing features high strength and low stretch and is unsurpassed in quality. A good compromise between thinness and the ability to make blind splice loops as suggested in our fly line set-up guide. It’s easier to knot than brands that are very thin but have too tight a weave for a blind splice loop.
