Absolute leaders are made with proprietary co-polymer blends that are designed to drastically reduce water absorption while maintaining an optimal suppleness for high knot strength. Absolute nylon leaders and tippet have a 29% higher wet knot strength compared to SA’s previous material and up to 40% higher wet knot strength when compared to our competitors. The new paper-based leader packaging is now 100% recyclable. All materials, inks, and window are fully biodegradable to protect our streams and reduce our environmental footprint.
