Berkley® NanoFil Uni-Filament Fishing Line It casts farther than any other Berkley line Superline strength, yet smooth as monofilament Near frictionless for long-distance casting Zero stretch offers superb sensitivity Incredible strength-to-diameter ratio Highly abrasion-resistant Beyond braid and monofilament, this next-generation fishing line casts farther than any other Berkley line. It’s made of gel-spun polyethylene woven with hundreds of Dyneema® nanofilaments that are molecularly linked to form a uni-filament that’s stronger than braid, yet smooth as monofilament. Dyneema fibers are nearly frictionless for shooting off spools and cutting through the air with little resistance, delivering unparalleled long-distance casting accuracy. Its zero-stretch performance eliminates kinking and spool memory, while offering premium bite-detecting sensitivity. It also features an incredible strength-to-diameter ratio. Highly abrasion-resistant for long-lasting durability. Made in USA.
