Berkley Trilene Ironsilk
Tough as iron, smooth as silk.
Now IronSilk is tougher than ever before.
IronSilk is a super-polymer—the first line with a built-in molecular reinforcing network.
Tough as iron: more than double the abrasion-resistance of other leading tough lines.
Smooth as silk: casts farther and more accurately than any other mono.
