Braided with a hollow core for fast and reliable splicing. Tight, round weave and uniform pick count (wraps per inch) for an exceptionally smooth surface that packs tightly on the spool with no flattening or digging in. FiberTech penetrates the weave and bonds with the individual Spectra fibers to stiffen and improve the handling characteristics of the line. Fine diameter minimizes line drag when trolling or fighting fish. 16-carrier construction results in incredible resistance to nicks and abrasions.
