If you're an urban dweller, you probably already know the necessities for daily life and getting around: comfortable shoes, good coffee, and a cool messenger bag. Girls can get away with purses for carrying their makeup and money and whatnot, but add a couple books and magazines into the mix for subway reading, and a purse just may not cut it. And guys definitely need a messenger bag. Even if they've got a girlfriend with a purse, I can tell you from personal experience, we do not have any extra room in there for your crap! Get your own bag! Or better yet, ladies, get your man a bag, like this one, which is all masculine raw rugged leather (Amazon, $140) . And guys? Get your lady a pretty bag like this olive green vinyl number with mint stitching (GreenergrassDesign, $68) and maybe, just maybe, she can manage to find room in there for your keys.
