Do you carry a 'bag', (messenger, backpack, shoulder bag), everywhere? If so, - What do you carry in it? - What kind of bag do you have, (backpack, messenger..?) Keys, Wallet, iPhone fit in pockets no problem. Add an iPad, 3x5 moleskin notebook, a usb stick, sub compact camera, sometimes my 13" MBP and other stuff then it's necessary to carry it all in something. I'm not a fan of man bags or carrying a bag everywhere, but if I want to bring things I need I have no choice .... There certainly is a lot of men who carry a bag everyday now. So far I've found a smaller backpack, (Eagle Creek Hitch), it works okay but a heck of a lot better that the few Tom Bihn bags I tried, (Ristretto and Amigo).
