Carhartt Ripstop Messenger Bag

Messenger bags are usually made of cloth (natural or synthetic). They are worn over one shoulder with a strap that goes across the chest, resting the bag on the lower back. Messenger bags are sometimes used by couriers; they are now also considered an urban fashion icon. However, if you feel comfortable with a backpack, then there is little justification for using a messenger bag. //@Anonymous: Just curious, what do you use a messenger bag for? Isn't it uncomfortable to carry compared to a backpack?
