Westin W6 ST3 Flourocarbon 35m

W6 ST3 Fluorocarbon sits right in the sweet spot between stiffness and flexibility. The ST3 rating gives medium stiffness, which helps with precise presentations while still allowing reliable, tight knots. This fast-sinking fluorocarbon gets your bait or lure down into the strike zone quickly, which is a clear advantage in deeper water, current, or when fish hold close to the bottom.

Thanks to its lower refractive index than standard monofilament, it is far less visible under water – perfect for pressured or clear-water fish. The small diameter to strength ratio means you can fish thinner leaders without sacrificing breaking strain. Available from 0.14 mm up to 1.20 mm, it covers everything from finesse rigs to heavy predator leaders.
