Quick take

Braided polyester backing that extends reel capacity and prevents line memory on fly fishing reels.

This Croch fly line backing is an eight-strand braided Dacron polyester line that goes on the reel under the fly line. The 30 lb strength suits anglers chasing larger freshwater fish or fish that run hard in current. It comes as two 100-yard spools, so you can fill a reel and keep a spare.

Best for

  • Trout and panfish on standard fly reels
  • Reducing memory coils in fly line
  • Fly fishing where a fast-running fish needs backing

Skip if

  • You fish only small streams where fish rarely run far
  • You need saltwater-grade backing for tarpon or stripers

Strengths

  • Small diameter lets you load long backing on smaller reels
  • Rot-proof polyester lasts for years
  • Braided construction resists fraying after cutting

Trade-offs

  • 100 yards fits reels sized for trout, not larger species
  • Polyester backing has less visibility than colored backing
  • Requires proper knot to attach fly line without slipping
