Developed with Seaguar's exclusive, proprietary Double Structure Technology, Fluoro Premier Leader is leading the market in innovation. Fluoro Premier has smaller diameters and increased strength vs. our FC and Red Label brand leaders. Fluoro Premier offers incredible knot and tensile strength and is an extremely soft line with low memory. Ideal for any leader fishing from 12 to 80 lbs, fresh or salt water. As with all 100% Fluorocarbon products, Fluoro Premier Leader is much less visible underwater than monofilament line and virtually invisible to fish. Fluoro Premier is also UV resistant, chemical resistant, non-absorbant, high-density and impervious to cold conditions.
