First post on the site. Glad to have joined the community. I've been a rock climber and backpacker for a long time, and I'm finally getting into mountaineering. I've been reading up on the essentials like crevasse rescue and the like for glacier and alpine travel, and I have come across somewhat conflicting information regarding chest harnesses. Some sources regard a simple webbing harness around ones chest essential for glacier travel in addition to the ever present waist and leg harness to protect the spine in the event of a crevasse fall. Others seem to disregard this and show only a basic harness with no connection to the chest. What do you all use when you are on the mountain? I want to be practical but I also want to be safe out there.
