Present your finesse rigs flawlessly to heavily pressured or line-shy fish with Berkley Vanish Fluorocarbon fishing line. Engineered specifically for ultra-clear water conditions, this 100% fluorocarbon line is designed to refract light exactly like water, making it virtually invisible underneath the surface. This line is highly flexible and softer than traditional fluorocarbons, minimizing coil memory and tangles to facilitate smooth, easy casting on spinning reels. Because fluorocarbon is completely non-absorbing and hydrophobic, it maintains 100% of its linear tensile and knot strength when wet. Its low-stretch formula provides sharp sensitivity to transfer light bites instantly to your rod tip while ensuring solid hook penetration during heavy hooksets.
