Old video, i know. But the easiest and best way to tell if the harness is the right side up is the orientation of the gear loops. They should point down... But the biggest mistake that you make and dont mention is. Dont put it on in a hurry. It's critical safety equipment, always take your time and pay attention to what you're doing.
Insulting a random human being from behind your screen who hasnt done anything wrong to you... i bet you vote Biden. This guy is just doing an effort to help the people that are new to this sport. Live and let live. And go read the Bible or watch a movie instead of insulting strangers over the internet.
