Westin W6 ST3 Fluorocarbon 0.219mm 50m 3.4kg Clear

Westin W6 ST3 Fluorocarbon — Near-Invisible Leader Line with Medium Suppleness

The Westin W6 ST3 (Stiffness Tier 3) Fluorocarbon in 0.219 mm / 3.4 kg is a versatile, medium-stiffness leader material that balances sensitivity and knot strength — ideal for anglers who need reliable, low-visibility performance across a wide range of species and techniques.

Near-Invisible Underwater Presentation

Fluorocarbon has a refractive index much closer to water than monofilament, making the W6 ST3 significantly harder for fish to detect. At 0.219 mm, this leader pairs beautifully with light to medium lure setups — whether you're targeting wary trout on clear chalk streams or finesse fishing for perch and zander in pressured venues.

Fast-Sinking, High-Strength Construction

The 100% fluorocarbon build sinks quickly, keeping your rig in the strike zone without delay. Despite the slim 0.219 mm diameter, it delivers a breaking strain of 3.4 kg with exceptional knot and abrasion resistance. The medium ST3 rating means it handles cleanly through guides, ties reliably, and retains enough stiffness to resist tangling and bite-offs.
