Sterling Rope's 11mm TriTech makes this lanyard highly abrasion resistant and durable. TriTech is designed with a unique Technora sheath, Dyneema inner jacket, and nylon cores. By combining the abrasion resistant sheath over a high strength inner jacket and pliable core, they have created a rope that is strong and durable, yet still supple enough to move and position easily. TriTech may provide additional resistance to incidental nicks and offers the most abrasion resistance with non-conductive properties.Sterling Rope's 11mm TriTech makes this lanyard highly abrasion resistant and durable.
