I need a suggestion for a bag that's good for city living! It needs to be:
- Relatively weather-proof (since I walk a lot)
- Can handle some wear and tear (it'll be jostled around in crowds/the subway)
- Not an easy target for theft! (no open compartments, must have zipper, etc)
- Can be worn on the shoulder (either is a shoulder bag or has detachable strap)
