P-Line Spectrex IV Braid Line Green 150Yd Spectrex is manufactured with the best raw materials available, exclusively using Honeywell Spectra®. The line is braided to P-Line’s exact specifications in the United States under very strict quality control standards. Unlike most “Superlines”, we use a coloring system that actually permeates the Spectra fibers ensuring great color integrity. So what does this mean to the angler who is not an engineer? Increased sensitivity because of near-zero stretch factor. Increased line capacity because of the high strength to diameter ratio. And a fishing line that has an unlimited life on the reel because in addition to being hydrophobic, Spectrex is also UV resistant.
