Quick take
An 8 strand hollow braided fly backing line rated for 20 lb, sized for trout and bass fly reels with salt-water capability.
This is an 8-strand hollow braided polyester backing for fly reels, spooled at 20 lb test and 108 yards. The hollow braid is slim, so more of it fits on a reel before the spool overfills. At 20 lb it suits trout, bass and most freshwater fishing. Choose it as the underlayer for a fly setup that needs a strong, low-profile backing.

Common questions
What breaking strength does the SF 20LB fly backing line come in?
The SF 20LB backing line is rated 20 lb test on this spool. That rating suits trout, bass and most freshwater fishing, so it works as backing for a standard fly reel. The spool holds 108 yards, which is about 100 meters.
Is the SF fly backing line hollow braided?
Yes. The SF 20LB backing is an 8-strand hollow braid made of polyester. The hollow construction keeps the line slim, so a 108-yard spool of it leaves more room on the reel for fly line.
How much backing does the SF 20LB spool hold?
The SF 20LB spool holds 108 yards, about 100 meters, on a single spool. Backing of this length fills a standard fly reel under a fly line, and the braid's good abrasion resistance helps it hold up to repeated use.
