Aerospace technology has been utilized to produce our TUF-LINEA(R) XP fishing line. Tension Lock Technology TUF-LINEA(R) XP is braided under high tension, creating more compaction of the fibers during the finishing process and a rounder profile than competitive lines. TUF-LINEA(R) XP is more compact, smaller in diameter, packs better on reels, offers better knot performance, casts longer, reduces rod tip wraps, and boasts higher abrasion resistance. TUF-LINEA(R) XPs state-of-the-art coating remains permanently bonded to the fibers, offering an incredibly long service life with zero shedding to become our best-selling braided superline.
