Reddit mentions of Osprey Men's FlapJack Backpack

Are you wanting a messenger bag or more of a back pack? I have the older version of the osprey flap jack pack, but the newer one still looks good. It doesn’t have a lot of different features but it is tough enough to go on day hikes but looks good for running around the city. It is easy to access pockets but the cover keeps everything protected from pick pockets. The water bottle holder on the inside is a little weird for some but I like that it keeps everything compacted together.

My usual carry is:
Dongles, ear phones (Bluetooth and regular), notebook, iPad and pencil, kindle, water bottle, folder for loose papers should I get any, battery pack, Kleenex, and a language die that helps me study Hungarian

I couldn’t find my exact bag but these are the new iterations:

That pack is deep enough to hold my 1.5 litter water bottle and everything with room to spare. I don’t suggest this sized bottle but I’ve grown to fond of it to change.

My $0.02:

This is what I use. It's not a camera bag, however I do use it every day and have my camera with me at all times. I have a small towel in the bottom where the camera lays. There's a big, long pocket on the side of the pack. I'm not sure what normal people use it for but it's perfect for a couple lenses (depending on size).

The main advantage of this is affordability and functionality that real camera bags don't have. I'm sure it wouldn't work for everyone. It doesn't really have any kind of 'quick access' you might find on a dedicated camera bag. I'll say again I literally just lay the camera in the bottom of the main compartment with a towel to fill up empty space. I walk to work and class every day, I've used this bag with camera on various camping trips to West Texas, Utah, and Montana/Canada. Unless you play football with it on you should not have issues damaging your stuff.
