Product Details Berkley Trilene Professional Grade 100% Fluorocarbon gives bass, walleye, and trout anglers a pro-level edge with a fast-sinking PVDF formula that boosts sensitivity when dragging jigs, fishing deep dropshots, or pitching finesse rigs into heavy cover. This line carries the toughness of Berkleys XT reputation with impressive shock strength for hard hooksets, abrasion resistance around rock and wood, and knot strength you can trust on controlled casts or long presentations. The fluorocarbons refractive index closely matches that of water, making it nearly invisible, and its low memory provides smooth handling on baitcasters and spinning setups, ensuring reliable performance across a wide range of techniques.
