You can made a simple harness from a single 4-5 m (13-16 feet) climbing rope as You may see in this tutorial but it's pretty uncomfortable. In this tutorial we add 3 protective parts made from paracord and rope to protect Your waist and thights.
We are using paracord 3 mm and Beal Edlinger Dry Cover 10,2 mm .
For harness use only climbing rope and read warnings at the end of this guide.
The harness has 3 protective parts: 1 for waist protection and 2 for thighs.
