TriPolymer Advanced monofilament utilizes a proprietary triple cross head extrusion process to incorporate Nylon 6, Nylon 6,6, and Nylon 12 into one advanced monofilament. A truly next generation fishing line. FeaturesLOW LIGHT REFRACTION TriPolymer Advanced Monofilament uses 3-layers of 100% Nylon polymer to create low light refraction properties very similar to Fluorocarbon. Fish won't see the line underwater. SUPER SMOOTH TriPolymer Advanced Monofilament's 3-layer tri-extrusion process incorporates the best properties of 3 different grades of Nylon. Strong Nylon 12, High Abrasion Resistance Nylon 6,6, and smooth Supple Nylon 6. A smooth surface unlike any other monofilament that casts further with very little friction through the rod guides. HIGHLY ABRASION RESISTANT TriPolymer Advanced Monofilament exhibits abrasion resistance that exceeds traditional copolymer monofilament and Fluorocarbon by up to 2X. Higher abrasion resistance equates to greater knot strength which means fe...
