The messenger bag started out in probably Aztec times, but in the 1400s for sure, then we went to envelopes delivered on a silver plate by the butler, then to carrier pigeons, then they became unreliable in the winter months so we got a postal service and then email and now we’re back to the messenger bag.
So since it looks like these guys are making a pretty strong comeback, if I were you I’d snag an Osprey messenger bag stat. Offered in a few colors and capacities is the Osprey Elroy Courier, the Osprey Veer, and the Osprey Warp. All and any of these are perfect for whatever activities you have planned, indoors or out.
Also available is the Osprey Flapjack and the Osprey Flapjill. It’s definitely a more stylish option for an Osprey messenger bag, but doesn't lose a bit of storage capacity and organization that the others have.
