With Orvis Super Strong Nylon Tippet, you can use lighter tippets to fool more fish without worrying about the tippet breaking. It has greater knot strength than any other nylon material, surpassing that of fluorocarbon tippet materials as well, and the highest tensile strength (psi) of any nylon material tested. Very supple, ideal for lifelike fly presentation, Super Strong is constructed of a copolymer resin material that was developed exclusively for Orvis and is sold by no one else. Includes a handy line cutter on the spool. Cancer and Reproductive Harm- www.P65Warnings.ca.gov. Type: Tippets.
