This Technora Survival Cord is the beefier big brother of our 450LB survival cord. Made from woven Technora, it has an amazing breaking strength of over 950 lbs. and has a PTFE coating for protection from the elements. Technora offers very high strength, low stretch, and abrasion-resistant material. Additionally, it’s coated with PTFE which provides both increased abrasion resistance and UV inhibition. This unique cord was originally developed for a US government agency to tether some sort of top secret airborne surveillance system. It is the strongest cord in the smallest package that will hold knots. This is a must-have for any survival kit.
