Made from 100% low stretch kernmantle nylon with a 41/59 sheath/core yielding incredible durability and handling. Great for multiple types of technical rescue such as, confined space rescue, USAR, and industrial safety applications. An added benefit to the SuperSatic 2 is the option of adding SafetyGlo. SafetyGlo couples the same sturdy construction of Superstatic with reflective tracers built in every few inches. The reflective traces come in handy in low light situations when light sources such as flashlights, car lights, or moonlight illuminate the rope for better visibility.
