AFW Surflon is 1x7 construction which means there are 7 strands of stainless steel wire wound together to form a piece of cable. Surflon has a tough but flexible nylon coating for additional corrosion resistance, reduced visibility, and longer overall life. The 7 strand construction allows for more flexibility for a more natural bait or lure action. Surflon is an excellent leader material for just about any toothy critter. Available in 30' spools. Tobacco brown color wire in a clear nylon sheath. Made in America!
