Beyond braid and monofilament, Berkley NanoFil Uni-Filament is next-generation fishing line that casts farther than any other Berkley line. Its made of gel-spun polyethylene woven with hundreds of Dyneema nanofilaments that are molecularly linked to form a uni-filament thats 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. Spool size: 1,500 yds. Lb. Test Dia. (in.) Color(s)4 0.004 Green, Clear Mist, Chartreuse 6 0.005 Green, Clear Mist, Chartreuse 8
