Airflo Micro Poly Backing - 30lb 175yds

Airflo Micro Poly Backing fills the space between your reel spool and fly line, helping your reel hold the right amount of line. It also gives you extra line when a fish runs beyond the end of your fly line.

This coated backing is a practical choice for everyday trout fishing. If you need greater strength for salmon fishing, or more backing capacity on a smaller reel, consider a stronger or thinner backing instead.
