This third generation monofilament blends 3 types of nylon to produce a fishing line that is super strong for its diameter allowing you to fish thinner and pull harder. This thinness gives great casting distance and combined with the Blue Sapphire colour, an invisibility close to fluorocarbon. Ultra Max Terpolymer has the suppleness needed to tie strong knots and resist abrasion 8 times better than standard monofilament.
