There are a lot of options, but there are a few that I use. I have a slew of bags I can use, but would throw these options out there. You mentioned your Mavic Pro, and then later said you wanted to transport your "M2"... I assume
Mavic 2, not
Mini 2, yes? I think the first thing is to determine how you want to pack your bag and what you want to carry in it.
The first picture is a Tamrac bag that measures 9x8x3". Too narrow for my
Mavic 2 but at times could be wonderful for my
Mini 2 as it can accommodate a shoulder strap or I can put it on my belt. No padding or protection on this one.
The second picture is the bag that came with my
Mavic 2 which I shlepped w/my
Mavic 2 Pro all over the east coast last year. The charger, accessories, etc were packed with my other belongings, but if I'm carrying a backpack, the case could go inside of it as well as the accessories in the bp separately. I pulled stuff up out of the bag so you could see that I was able to carry ND filters, a bracket (which I only use with my iPad. Note strobes mounted on the rim. Unseen is the 3rd battery in the compartment below the 2nd. I love this bag as it makes for quick deployment, easy carry, decent protection and room for lots of accessories for such a small size. Its even better with my
Mini 2 and I won't need to buy a new bag when I get a
Mini 3. 7x8x6.5".
Last photo shows a bag I found on Amazon. $19.
When I was a professional photographer, before digital, I carried stuff on my shoulder during assignments, probably similar in size to what you're looking for and was surprised to find what I needed at Kmart for under $10. I stiill have them and use them. It doesn't necessarily have to be a brand name like Tamrac or Lowepro. A lot depends on how much protection you need with the drone inside the bag.
