I use the hunter safety system. I needed it because i had to get 30 to 40 feet in a tree to be above a ridge. Talk about scary, being that high. I usually put it on at the truck and walk it with it on. The two straps that wrap around your legs are seat belt buckels. the two in the fron tof the chest is a hard plastic clickers.
I would buy a little bigger size because when your wearing alot of clothing it does get a little tight.
