I used my bag on a trip to NYC and it was able to hold everything I needed without a problem. I also liked how long you can make the strap for crossbody wear as lots of other crossbody bags have very short straps on them. The only problem I had with the bag is that the key holder in the bag broke but I'm still going to keep it.

this is a great little purse/messenger bag, it is kind of between the two on size. when you lift up the flat there is a great organizer pockets for ID and cards, i was using mine for business cards as i would still keep my credit cards, etc in my wallet inside. the main pocket is big enough for an exta layer if it is a thin layer, like a thin merino wool layer or something. Not saying everyone walks around with one of those, but to give you an idea it would be big enough for that plus your wallet, keys, cell phone, checkbook, and a few extras. Not huge, but big enough. Also the strap gets plenty long to go over the shouler/across the chest style.
