Berkley Vanish Fishing Line is a fluorocarbon line that will give you the edge on your next trip on the water! New and improved, Vanish is now softer and more flexible which makes it easier to work with as your main line on both casting and spinning gear reducing line twists and tangles. Virtually invisible, Vanish disappears in the clearest of water to provide you with a stealth-like approach for finicky fish!
