I attach the SoloAid to my harness using one 12" Blue Water 27kN sewn spectra runner. I prerig this by threading the end without the seam (B) through the small hole at the bottom of the SoloAid so that a short loop sticks out.
Step #1: To attach the SoloAid to my harness, I take end (A) of the runner and pass it through my waist and leg loops. I then thread end (A) back through the short loop (B).	Step #2: I now pass the loop of end (A) over the whole SoloAid assembly.
Step #3: The finished knot is compact and secure. It also is simple to tie and untie. Lastly, it keeps the SoloAid close to your center of gravity.
