Westin W6 ST3 Fluorocarbon 0.19mm 50m 2.2kg Clear

Westin W6 ST3 Fluorocarbon — Near-Invisible 0.19mm Leader Line for Light-Line Precision

At 0.19mm and a 2.2kg breaking strain, the Westin W6 ST3 Fluorocarbon is built for anglers who need a fine, fast-sinking leader that disappears underwater without sacrificing strength or sensitivity.

Medium Stiffness That Balances Control and Knot Strength

The ST3 (Stiffness Technology 3) rating sits at the midpoint of Westin's ST1–ST5 stiffness scale, delivering a practical balance between the precision-casting control of stiffer lines and the superior knot strength of more supple ones. At 0.19mm, this translates to confident presentations on light tackle, reliable hook-sets, and knots that hold under pressure.

Fast-Sinking and Near-Invisible Below the Surface

Fluorocarbon's lower refractive index means this line bends light far less than comparable monofilament, making it significantly harder for fish to detect. Couple that with a fast sink rate and you reach the strike zone quickly — a real advantage in clear water or when targeting wary fish at depth.

Choose the Right Variant

The W6 ST3 Fluorocarbon is available across a wide diameter range, from ultra-fine to heavy-duty, so you can match the line precisely to your target species, presentation style, and conditions.
