Scientific Anglers Backing Dacron 20 lb, 100 yd – Yellow

Overview

Scientific Anglers backs this Dacron line as a purpose-built backing option. The 20 lb test, 100 yd spool comes in bright yellow, chosen for high visibility during line handling on the water. The braided construction delivers a dependable feel in your hands, whether you’re filling reels or preparing for a day on the water.

Thin profile and visibility

The extremely thin braid creates a compact backing that feeds through guides with minimal bulk, supporting smooth line flow during casting and retrieval. The yellow color remains visible under varying light, helping you monitor line movement and tension at a glance.

Durability and reliability

High abrasion resistance helps the backing withstand rubbing against reels, guides, or shoreline obstacles. The braided Dacron fibers maintain integrity under repeated pulls and friction, offering predictable performance across sessions and seasons.

Practical uses on the water

Use this backing to fill reels and connect to your primary fly line. With 100 yd of length, the backing provides ample material for multiple setups, making it suitable for common freshwater rigs and some light saltwater applications.

Care, storage, and tips
