Unlike traditional monofilament, McCoy Premium Co-Polymer Fishing Line is formulated using a proprietary blend of nylon resins and infused with our Penesil Saturation Process (PSP). This advanced technology delivers longer, smoother casts, superior abrasion resistance and eliminates water absorption for longer life and durability.  Excellent visibility above water for easy detection while remaining virtually invisible below. McCoy’s CBF emits a luminescent glow when used with a black light making it perfect for night fishing.
