Berkley Sick Fluorocarbon Leader 0.18mm 2.3kg 50m Clear

Berkley Sick Fluorocarbon Leader 0.18mm — Near-invisible protection for finesse presentations

The Berkley Sick Fluorocarbon Leader combines stealth and durability in a supple 0.18mm leader material. Engineered for trout, perch, and zander fishing in structure-rich waters, this fluorocarbon stays nearly invisible underwater while delivering high knot strength and abrasion resistance against mussels, rocks, and snags.

Nearly invisible underwater for spooky fish

Fluorocarbon's refractive index closely matches water, making the Sick FC Leader almost undetectable to wary trout and perch. The 0.18mm diameter (0.007 in) keeps your finesse presentations natural while the clear finish disappears in rivers, lakes, and streams.

Abrasion-resistant and knot-strong for structure fishing

Rocks, zebra mussels, and submerged wood put constant stress on your leader. Berkley Sick Fluorocarbon resists abrasion better than monofilament and maintains excellent knot strength at 2.3kg (5 lb) breaking strain. The supple construction ties easily and allows lures to swim freely with minimal stiffness.

Match your leader diameter to target species, lure size, and cover density. All variants come on convenient 50m pony spools.
