RE: ever use a safty vest harness?
I got one for my son. He was new to hunting and treestands and I felt that it was about the safest and easiest way to go. Very happy with it. It is easy to step into and put on and strapping to the tree is no problem. He is really comfortable in it. Only probelm, that isn't really any problem, is all the extra strapping. I have it wrapped around itself to take up the long ends. So far it has worked well and for my son. For me, it is piece of mind that my son is well strapped in.
I still use one loop around my waist and one around the tree. Might find me hanging upside down someday. I just don't like the feel of any harness including the vest.
