Forget everything you know about monofilament. KastKing® TriPolymer Advanced Monofilament Fishing Line redefines the concept, combining 3 different nylon formulations into a tri-extrusion blend that rivals fluorocarbon for underwater stealth, has superior strength and abrasion resistance, and is exceptionally smooth, soft, and easy to handle. Its supple Nylon-6 inner core, high-strength Nylon-6.6 mid-layer, and extra-tough Nylon-12 outer layer work together to give you a mono line that's twice as durable as any single-extrusion mono. And on average, KastKing TriPolymer Advanced exhibits up to 12% lower stretch than copolymer mono as well, for better feel and stronger hooksets. Smooth and quiet through the rod guides, too! A step up from both standard monofilament and fluorocarbon – try it today!
