As the longest-casting, thinnest, strongest, and most sensitive line on the market today, Berkeley NanoFil allows you to go lighter than ever before, to throw small spinners farther and to finesse small baits with greater ease. Not a mono, not a fluorocarbon, and not a braid-NanoFil feels and handles like a smooth monofilament with the performance characteristics of a braid. Thin, smooth texture, minimum diameter, and maximum strength for effortless casting precision and distance without sacrificing performance. NanoFil consists of hundreds of Dyneema gel-spun polyethylene nanofilament fibers molecularly linked and shaped into a unified-filament fishing line, giving it superline-class strength. Zero stretch and ultra-small diameter provide ultimate sensitivity to feel everything from the lightest pickups to the most jarring strikes. Zero memory virtually eliminates line tangles. Incredibly high strength/diameter ratio. Designed for use with light- to medium-weight spinning tackle. 150-yd., 300-yd., and 1500-yd. Spools. Clear Mist. 1, 2, 3, 4, 6, 8, 10, and 12-lbs. test.
