Invest in a molle assault vestA real photographers vest is perfect for all the stuff photographers use. I have two so I acknowledge the utility of cargo vests of all sorts.
That said, I no longer use them for anything for two reasons.
First, they look silly unless you're actually engaged in photography and even then only journalists and hikers who use view cameras get an unconditional pass.
Second, mine are far too big for me. They'd probably slip off my shoulders and fall right down to my ankles. I bought them over 200 pounds ago and now that I'm back down to what I weighed when I was 20 years old, they just swallow me up.
