So, american camera bag manufacturer F-stop, makes THE best camera bags on the market (that's my opinion but also the truth). I've had their Mountain Series Loka for a while now and it's an amazing backpack, though a little too big for walking around in the city with a smaller kit like my Fujifilm X-T1 + lenses so I was looking for something smaller.
And since I've already established that F-stop makes the best camera bags on the market, why look at any other brand? F-stop also has another line of bags called the Millar Series which has just undergone a face lift. The Millar Series is a line of bags more targeted for the urban photographer and I found a sling bag called the Brooklyn Sling. This bag so far seems as well made as the Mountain Series, just a bit different. It's made of weather proof Cordura Nylon, with a padded inside with movable dividers (like any other camera bag I know of). There are also two small compartments on the inside of flap that closes the bag, where I keep spare batteries, cleaning cloth and memorycards, These are rather small, but holds the things good. There is also a compartment on the outside of the flap where I usually keep my iPod. On the outer side of the bag there's also another just a little bit bigger compartment to keep other things. The shoulder strap (or whatever to call it) is wide at the upper end and then gets more narrow further down and on it, there's a compartment for a phone or small compact camera or similar. On the backside of the bag, the bit that's resting on your back, there's a compartment for an iPad or 11" tiny laptop.
Is there anything more, well, not really. There's an extra strap that can be attached or removed that will prevent the bag from sliding to the right while on a bike for example. The bag in itself is very light and holding my Fujifilm X100T, Fujifilm X-T1, Fujinon XF 14mm f/2.8 R, Fujinon XF 35mm f/1.4, Fujinon XF 56mm f/1.2, spare batteries, memorycards, lens cloth, weighs around 3 kilos and with such a light setup it's easy to walk around the city for a whole day.

BTW, I'm not paid by F-stop (unfortunately) I just find their stuff being pure awesomeness...
