Yo-Zuri Hybrid Copolymer Fishing Line - The Yo-Zuri Hybrid Copolymer Fishing Line is the first and only fishing line that molecularly bonds nylon and fluorocarbon during extrusion. The Yo-Zuri Hybrid extrusion is 100% waterproof with the abrasion resistance and sensitivity of fluorocarbon but incorporating the flexibility and stretch of nylon. Co-Polymer Consisting of Fluorocarbon and Nylon Molecularly Bonded During an Exclusive Extrusion Process Abrasion Resistance and Sensitivity of Fluorocarbon Flexibility and Stretch of Nylon UV Resistance 100% Waterproof Low Memory
