Berkley Sick Fluorocarbon Leader 0.40mm 12.6kg 50m Clear

Berkley Sick Fluorocarbon Leader 0.40mm — Near-invisible protection for predator fishing

The Berkley Sick Fluorocarbon Leader 0.40mm combines exceptional knot strength with underwater invisibility, making it the reliable choice when targeting trout, perch, and zander in demanding freshwater conditions.

Almost invisible under water

Fluorocarbon's refractive index closely matches water, rendering this 0.40mm leader nearly undetectable to wary predators. Fish approach your presentation with confidence, especially in clear water or high-pressure venues where leader-shy species demand stealth.

Built to withstand abrasion

Fishing near mussels, rocks, and submerged structure is where most leaders fail. The Sick Fluorocarbon's abrasion-resistant construction protects against sharp edges and rough bottom contact, extending the life of your rig and preventing break-offs when fish dive into cover.
