A back cinch would help some, yes. It depends on how steep the hills are that you're riding down. If they are super steep, a back cinch wont keep it from sliding over your horse's neck, but it will keep it from popping up really bad in the back. Regardless you would need a crupper in such a case.
Another idea would be to look around for a britching. It's typically used on pack horses, but when i went up to the mountains the other year I had to borrow one from a friend because my crupper broke.
Looked like this
"If a horse fails to do something that is because he was not trained to do it. If a horse fails to do something properly that is because he was not trained properly."
