SF Braided Fly Line Backing – Orange, 20Lb
SF offers a compact, eight-strand hollow braided backing designed to maximize line capacity and reduce friction at the reel. The 20 lb variant is ideal for trout and similar freshwater species where a thinner backing helps fill the reel without overfilling. The material is described as rot-proof, UV-resistant polyester, providing long-term durability against sun exposure and abrasion from overhanging vegetation or rough shoreline environments. This backing works well with standard fly lines, offering a smooth splice and reliable knot performance. Anglers can expect strong abrasion resistance, with low fray after cutting and attachment, ensuring a dependable foundation when fighting sizeable fish. The soft weave maintains an easy knot, which helps preserve line integrity near rod guides during rapid retrieves or aggressive hooksetting.
For users seeking color-coded visibility, the orange variant can improve tracking of line movement in low-light conditions or choppy water. While designed to be a complement to fly lines, its low friction helps reduce wear on rod guides, contributing to a longer rod and reel life. This backing is suitable for a range of freshwater fishing scenarios and can support a variety of line setups before spooling.
SF Blue Backing Line – 20Lb, 100m
The blue variant from SF uses the same eight-strand hollow braid construction, prioritizing abrasion resistance and knot reliability. This 20 lb backing is suitable for mid-range fly reels and applications where a balance between line capacity and strength matters. The polyester composition provides resistance to rot and UV exposure, extending service life in sunny or salt-spray environments. Anglers can benefit from the backing’s low coefficient of friction, which helps preserve rod guides and reduces snagging during casts and retrieves. The bright blue color improves visibility against the water, aiding in line management on windy days or fast-running currents. This option is well-suited for trout, bass, and similar freshwater species where maneuverability and smooth splicing are crucial.
Like other SF backings, it is designed to be cut and tied with minimal fraying, ensuring clean joins when attaching to main lines or leaders. A dependable option for anglers who value a balance between performance and reel capacity without paying a premium for heavier lines.
RIO Dacron Fly Line Backing – 20Lb, 200yd
RIO’s Dacron backing is a traditional choice that emphasizes strength and low stretch, making it a reliable option for big-water fishing where line memory and consistency matter. The 20 lb rating aligns with a broad range of freshwater species, offering a compromise between thinness and the ability to perform blind splices when necessary. The backing is designed for easy knot tying and smoother splices, which helps reduce resistance during the line’s passage through the rod guides. Anglers who value a predictable feel and straightforward setup often select this backing for its proven performance in a variety of reels and line configurations. The chartreuse color is also a practical option for visibility during long casts and in varied water conditions.
This backing is compatible with many fly lines and reels, delivering dependable knot strength and a traditional feel that many anglers associate with tried-and-true backing choices. It is particularly suitable for anglers who prioritize a straightforward, consistent splice process and robust performance under pressure.

Ideal for freshwater species and medium-to-large fighting fish, this backing balances strength and visibility while maintaining manageable spool capacity on the reel.
Buying Guide: Key Considerations For Backing Lines
Backings vary in construction, strength, length, and visibility. When choosing a backing line, consider the following:
- Material and construction: Eight-strand hollow braids offer smooth joins and good abrasion resistance, while some Dacron options prioritize low stretch and high strength.
- Breaking strength: Common ranges are 20 lb and 30 lb. Higher strength supports saltwater or big-game pursuits but may reduce spool capacity on smaller reels.
- Length: Longer backing adds capacity and allows for larger reels and longer drifts. Typical lengths range from 100 to 200 yards.
- Visibility: Bright colors (orange, chartreuse, yellow) improve tracking and line management in variable conditions but can also influence stealth in clear water.
- Knot and splice performance: Backings should splice cleanly with minimal fraying and maintain integrity under load during a fight.
- Durability under sun and salt: UV resistance and rot-proof materials extend life in sun-exposed or saltwater environments.
- Compatibility: Ensure the backing is compatible with your main fly line and reel capacity, including spool-fill considerations.
Bottom line: The best backing for your setup depends on your target species, reel capacity, and preferred visibility. For trout and freshwater reels, a 20 lb backing with good knot performance and abrasion resistance is usually sufficient. For larger freshwater species or mixed environments, consider higher strength options or longer lengths. For saltwater or pike fishing, evaluate backings designed for higher bulk and extra fill on reels, ensuring smooth splices and consistent weaving.
