Airflo Micro Poly Backing

Airflo’s Micro fly line backing is a Braided Polyester that has an extremely low diameter, low stretch and is 100% rot-proof. The super smooth braided backing sits flat on your fly reel or spool, allowing you to pack as much fly line backing onto your reel as possible. With an extremely high knot strength this is the perfect option for filling your fly reels.

Available in two breaking strains:

• 20lb is perfect for filling smaller reels with lower backing capacity reels, or filling large reels with a greater length of backing.
• 30lb backing is the quickest and easiest way to fill cassette reels or large saltwater reels.
