I was reading up on rock climbing harness and it seems not all of them have weight bearing loops in the back.

I like the idea of a RC harness from the research I've done so far.
Hardly anyone that has switched has gone back to a full body harness.

I've already tried mine out. The lanyard attaching in the front is going to work great. Plenty of slack, not in the way at all, and in case of a fall I will be facing the tree. I think I'm going to like it.

The average rock climbing harness is not made for extended lengths of time suspended or is there any proof otherwise. It is more of a temporary relief to re-position or from falling to the ground. Would you not need the wide under leg straps and a suspension relief for standing up to relieve trama just in case of a long time before rescue?
Just not much test on harnesses it seems to provide time frame before trama with different harnesses.

You can hang/sit in a rock climbing harness indefinitely without worry of suspension trauma. I can put my hand between my leg and the top of the leg straps when sitting in it. It puts Zero pressure on the femoral arteries. That was the entire reason I made the switch to begin with.

My HSS is a little small now and this may be my new choice. Appreciate info.

Not suited very well for fall protection. It's use is for static use. OSHA many years ago after multiple studies made waist belts illegal for fall suppression due to spinal cord injury. Essentially, the shock of the stop was breaking peoples backs, hence the development of the full body harness. some fall protection is better then none, but just be aware that you may end up paralyzed for that small convince. Also, fall restraint must have a 5,000 psi breaking strength. What is the rating on these?

Gomerpyle, is that the Vario Speed harness?

There is no way anyone (and all of my buddies use them and have tried) can convince me something coming out of your crotch is less in your way than mine between my shoulder blades
