Our original “salt and pepper” line, TUF-LINE® is manufactured with Spectra® fibers and has an amazing 4% stretch which translates into super sensitivity and more powerful hooksets when compared to monofilament. TUF-LINE® is also hydrophobic, meaning it repels water and won’t swell in diameter. TUF-LINE® is over 40% smaller than equivalent test monofilaments, which substantially reduces line drag. Featuring a unique bi-component construction that combines the ultimate knot strength with the highest abrasion resistance creating The Ultimate Fishing line, which is how TUF-LINE got its name.
