Proprietary Extrusion Process Destron Monofilament Fishing Line utilizes a proprietary extrusion process using Nylon resins to create a premium advanced monofilament fishing line. Lower Light Refraction Destron Monofilament Fishing Line made with 100% Nylon resins exhibits lower light refraction properties than standard copolymer fishing line. Ultra-clear monofilament fishing line. Super Smooth Destron Monofilament Fishing Line has a super-smooth surface that allows for further casts with very little friction through the rod guides. Highly Abrasion Resistant Destron Monofilament Fishing Line has higher abrasion resistance than most traditional copolymer monofilament. Higher abrasion resistance equates to greater knot strength which means fewer lost fish due to line failure. Low Stretch Destron Monofilament Fishing Line has a lower stretch factor that averages 12% lower than most traditional copolymer monofilament. Lower stretch allows you to feel even the slightest bite.
