Field Notes

Fly line backing is used on the reel arbor under fly line to increase spool capacity and provide extra reserve line for long runs. It is most practical for fly fishing setups where you need a strong, thin backing layer before attaching the fly line.

Pros

  • Provides extra line capacity on fly reels
  • Strong 20 lb backing for hard-running fish
  • Useful for both freshwater and saltwater fly setups

Cons

  • Not a standalone fishing line
  • Requires proper knotting and reel spooling
