This 100% fluorocarbon tippet is designed with a unique two-layer construction, providing up to 33% higher knot strength. A softer fluorocarbon outside layer helps knots seat properly and increases overall knot strength, while the harder fluorocarbon core provides exceptional tensile strength. Supreme Fluorocarbon tippet is also more supple than most other options, providing better drag free drifts while maintaining a stealthy footprint. Supreme Fluorocarbon is available on a patented cutter spool with SA's improved tippet band for easy identification and dispensing.
