Excellent flexibility, torque-free, superb handling double braid with HTS 78 core and proprietary coating that splices and tapers easily. Endura Braid combines a low-stretch core with the long-lasting durability of a polyester cover. Great for applications needing less stretch than allowed by Sta-Set, but more affordable than Vectran or Technora braids.
