Virtually invisible to fish, Orvis Mirage Pure Fluorocarbon Trout Tippet paves the way to fly-fishing success better than any other tippet material. It has a specific gravity of 1.76, nearly twice the density of water, which means that it will belly below the surface film, eliminating any shadows that might spook the fish below. Made of the worlds strongest pure fluorocarbon material, Orvis Mirage does not absorb water, so it retains its superior knot and tensile strength in all conditions. Abrasion-resistant, impervious to UV breakdown, its simply the best fluorocarbon tippet available. Available: 6X, 5X, 4X, 3X. Cancer and Reproductive Harm- www.P65Warnings.ca.gov. Type: Trout Tippet.
