I use an upper body climbing harness, an example here,

I have a snap hook on the front and attach the camera to that.
I like this setup as it puts the weight on both shoulders and the camera is on my chest.
I can carry the camera attached to my tripod across my body in front of me and swing it into place if I have to move around although for any distance I put the combo on my shoulder.
Seeing parents with very young kids on their chests, and to an extent the Cotton carrier product had me looking at the climbing harness.
I also use the harness with my monopod with the Wimberly head in the manner of a flag standard harness. I use a PVC plumbing pipe cap on a
cord, ( length adjustable to fit), as a cup for the foot of the monopod which gives me easy mobility as the weight is on my shoulders and against my chest.
Took a bit of time to get used to it but now it is my normal rig.
