Made with ultra-high molecular weight polyethylene, the worlds strongest fishing line material that is 4 times stronger than nylon. The new WX manufacturing method has been achieved to exceed the normal PE line. Dramatically Improve Linearity, Surface Slip High density 4-ply (HD BRAID) greatly reduces the coefficient of friction. Made with a highly functional PE line that provides casting performance, speed of line dropping, and reduced guides chafing noise.
