Westin W6 ST3 Fluorocarbon 0.92mm 20m 49.2kg Clear

Westin W6 ST3 Fluorocarbon — Heavy-Duty Leader Material with Near-Invisible Presentation

Built for anglers who demand both brute strength and low visibility, the Westin W6 ST3 (Stiffness Tier 3) Fluorocarbon in 0.92mm delivers 49.2kg breaking strain on a compact 20m spool — purpose-made for heavy leader and trace applications in freshwater and saltwater alike.

Near-Invisible in the Strike Zone

Fluorocarbon bends light in a way that is far closer to water than standard monofilament, making this leader material significantly less detectable to wary fish. Combine that with a fast-sinking rate and your presentation reaches depth quickly, keeping you in productive water without unnatural drag or surface interference.

Medium Stiffness, Maximum Knot and Tensile Strength

The ST3 stiffness rating sits at a balanced midpoint: supple enough to tie secure, reliable knots yet stiff enough to resist coiling and tangling around hooks or rigs. At 0.92mm diameter with a 49.2kg breaking strain, this leader handles the demands of big-fish fishing — large pike, catfish, saltwater predators, and sharks — where both abrasion resistance and knot integrity are non-negotiable.

Choose the Right Variant
