The most flexible, easiest casting fluorocarbon. 100%
fluorocarbon has a similar refractive index to water, so fish can't see
it. Best Vanish formula ever, with 20% better shock strength, improved
knot strength and easier to handle. Non-absorbing fluorocarbon maintains
strength and abrasion resistance underwater.
