Scientific Anglers Fluorocarbon Leaders are invisible underwater. Constructed of a UV-proof material with high abrasion resistance, these leaders are great for wary fish, low-water conditions, and truly excel when nymphing. But did you know theyre also great for dry-fly fishing? Just an added bonus. They feature the highest wet knot strengths in the industry and true-to-spec X sizes.

Lowest visibility available Optimal abrasion resistance Refractive index simulates that of water, resulting in ultra-low visibility to fish UV rays have no effect on strength of the material, even after prolonged exposure to the sun
