Double Rope Technique (DRT) is used to self belay the climber in such a way that the rope can be retrieved without going back up the tree. One end of the rope is fastened to the climber's saddle (harness), from there the rope passes around the tree and back to a friction hitch which is also attached to the climber. This system allows the climber to easily adjust the rope to provide a belay if free climbing, or to go up or down if hanging on the rope. As long as there is minimal slack in the system, any fall will be restrained.
