I wanted to buy my son the vest style harness because they looked easier and more comfortable, but they were backordered and I needed one for this weekend. My only option for a kid was seat-o-pants. Well I received it today and harnessed him up. We went out where we hang deer and tied him on the pulley, he climbed the ladder and I held the rope and told him to jump. I finally got tired of holding the rope and made him quit, I even left him hang while I anwsered the phone for ten minutes. Very comfortable and easy to put on. I would recommend it, and Mom is going to feel better.
