I would hate to be hanging from a tree with a single strap around my chest. I purchased a vest style harness a couple years ago, it is very easy to put on unlike the spider web harnesses that they give you when you buy a treestand. I don't know the brand of the one I have but several have come out since I bought it, probably with some improvements. Mine was about $80. It's very comfortable, you don't even know its on. And because of the ease and comfort, I wear it much more often than when I was trying to figure out the old style ones. It actually was the reason that I was able to shoot my bow buck this year, it came in behind me so I had to swing myself our over the left side of my tree and have the harness hold me in place as I shot.
