Inconspicuous Bag?

Thanks! Most of my travel will be at night along the south side.

I have Tamrac Rally. It is my everyday bag for something like ten years now. Not a camera bag, but everywhere, everything I need bag. It doesn't scream anything. But it is camera bag inside. DSLR, two lens - no problem. I have Graflex camera in it once with tripod attached on the bag belt, plus film holders, plus water and else.
I'm going shopping, hiking, traveling and so on with this bag for all of this years. It doesn't look trashed, yet .

Domke bags are pretty inconspicuous. Perhaps something like the F-5XB in one of their ruggedwear finishes, like military green or brown would do the trick. Pretty inexpensive, too.

Update:

Returned from trip alive and with all my equipment!

I ended up going with a small, black, military-style backpack. At the bottom of the bag I had my two small primes each in it's own zippered lens case. Resting on top of them was my D750. The biggest problem I had was unzipping the backpack to get to my camera. The zipper was not easy to open and would get stuck near the curvy areas of the backpack.

In terms of crime, I felt I did the right thing. I ended up in at least 3 situations where where I felt uncomfortable; felt I was being "cased" (once on the subway, twice on solitary streets I mistakenly ended up on). Same vibe I have gotten in the past before being robbed at gunpoint.

My biggest regret was taking the "flashy" D750. I wish I would have taken a tiny point & shoot instead as I would have gotten the same images (98% of my images were shot with my Nikon 24mm f2.8 AF-D prime). I refrained from taking many pictures because I didn't want to take out the D750. Next trip will be (hopefully) to NYC to visit Coney Island via subways. Looking to get a pocketable point & shoot that will fit easily into my pocket and capable of capturing nice images (my old Lumix LX3 won't fit in my pocket ).

I bought a beat up used on purpose very similar to this

looks like a pair of old jeans.. Can hold three lenses DSLR w/ 70 -200, 16-35 and 24-70

I wandered around Tijuana with a Domke F-5xb, Fuji X100F and Minolta XG-1. (X-700 in place of the XG-1)

I know this is probably too late for the OP, but I just picked up this Estarer messenger bag. I plan on taking it to Key West with my new EOS R + RF 24-105L, M50 + four EF-M lenses, iPad, Kindle and various photo accessories (batteries, chargers, memory cards, CPL filter, etc.).

I have one of these bags. I like it very well and it doesn't scream "camera"

Most hardware stores have very strong extra thick zippered bags for tools. With some dry bags, creative thinking and padding this may work.
A tough Carhartt lunch bag (construction workers use these) may be as good or better and much less obvious. Just taking lunch to work appearance. Also
