This exceptional leader and tippet material is made from 100% fluorocarbon (PVDF). Fluoroflex Plus is some of the strongest, thinnest fluorocarbon on the market with incredible strength; for example, 5 lb for 5x material. It is a slightly softer material than Fluoroflex and ties excellent knots. The refractive index (1.42) of Fluoroflex Plus in water (1.33) compared to nylon (1.62) makes it almost invisible to fish. Fluoroflex Plus, with a density of 1.72 (compared to nylon of 1.15), sinks quicker and gets below the surface tension for more effective dry fly, nymph and wet fly fishing.
