Cordage is a vital tool; it has endless potential uses

Parachute cord, also known as paracord, is a versatile and strong type of cordage that is popular among outdoor enthusiasts and survivalists. It is lightweight and durable, making it ideal for a variety of uses, such as setting up shelters, securing gear, and even as a makeshift fishing line. It is recommended to carry a minimum of 50 feet of paracord on outdoor adventures as it can come in handy in a variety of situations.

In 2009 when I walked 650km from Resolute Bay to the North Pole over frozen sea ice, hauling my pulk, loaded with a winter tent, food, fuel heating stoves, extra  clothing, shovel, extra fuel, etc. I used a waist harness with a trace of Shock Cord (bungee cord) attached directly to the pulk. 

The Shock Cord did not freeze as most ropes do ; more importantly the elasticity of the trace saved my back from injury caused by the constant jarring especially when we encountered ice rubble fields stretching for most of the journey.
