Cortland Gel Spun Fly Line Backing - 300 Yards, 50 lb, Hi-Vis Yellow

Meet Cortland Gel Spun Fly Line Backing

Designed with strength and consistency in mind, Cortland's Gel Spun backing uses high‑strength gel‑spun fibers braided to exact specifications. The result is a smooth, uniform diameter that helps you manage backing confidently as you cover long runs or explore new water.

The backing features a tight, round braid that maximizes capacity, letting you pack more backing onto smaller spools. This design minimizes the need for frequent splices and reduces interruptions during a day on the water, enabling more time focused on your cast and presentation.

Choose from hi‑vis color options—yellow, pink, blue, and white—across tests of 30‑lb, 50‑lb, and 80‑lb, on both 300‑yard and 2500‑yard spools. The bright colors enhance line tracking in bright sun, low light, or over choppy water, helping you monitor take-ups, taps, and line movement with greater ease.

Key benefits

• Gel‑spun fibers provide high strength and durability for reliable backing under tension.
• The tight round braid maximizes yardage on smaller spools, reducing the need for frequent spool changes.
• Bright hi‑vis colors improve visibility during various light conditions and water tones.
• Available in 30‑, 50‑, and 80‑lb tests on 300‑ and 2500‑yard spools to suit different setups.

Practical use and setup tips

When spooling, aim for an even fill to maintain a consistent diameter along the spool. Pair this backing with a compatible fly line for smooth transitions, and store spools in a cool, dry place to preserve braid integrity.

• Check backing tension and fill level periodically to prevent tangles and ensure smooth casting.
• Use the color option that offers the best visibility for your typical fishing conditions.
