Sufix Big Fish is a braided line that conforms to all IGFA class requirements. It consists of HTP braid (high tenacity polyester braid) which increases break strength and abrasion resistance while adding density for faster sinking speeds.It has a heavy wax impregnation which protects the line from nicks, cuts and chafes and eliminates strength loss from knots and splicing. It is great for bluewater trolling.
