Obviously, they are made to protect the upper body, but to what degree? I tend to land on my shoulder in most falls. In the past, I have dislocated my shoulder, more then once, and broken my collar bone. Will a vest help me at all in those areas? I ride a lot of green horses and as I get older, I worry more about getting hurt. I don't need recommendations as I have read all the posts on this forum, just advice on how well I will be protected.
