Saw those. Looked attractive and comfy. Just didn’t know if they screamed “gun” when you wear one ... like a fanny pack or a “photographer’s vest” with no camera gear.
Still a good option anyways though.
I have a western levi vest, and wear a broach that screams “grandma!” Excellent camoflage, and the vest is all-weather. May not work if you’re a man. Then again....
When my kids were babies, and I was out with them and wife, I would wear a photog vest. I would put a couple of disposable diapers in the left pocket, a baby bottle with water sticking out a handy right-side pocket, and it would be my "daddy vest". Women would look and exclaim what a neat way to carry all the baby stuff conveniently...
