Developed with Seaguar's exclusive, proprietary Double Structure Technology, our FC Blue Label Leader is one of the best on the market. Our fluorocarbon leaders' advanced strength allows use of smaller pound test vs. other fluorocarbons for more effective presentation. Seaguar Blue Label has incredible impact strength, knot strength and abrasion resistance and is ideal for any leader fishing from 2 to 80 lbs., fresh or salt water. As with all 100% Fluorocarbon products, FC Leader is much less visible underwater than monofilament line and virtually invisible to fish. FC Blue Label is also UV resistant, chemical resistant, non-absorbant, high-density and impervious to cold conditions. Made from 100% Seaguar resins and produced using our proprietary extrusion process.
