For added peace of mind on long bus or subway rides, we load our day's essentials in the Pacsafe Metrosafe LS450 Econyl Backpack. The zippers can be clipped or locked to safeguard against unwanted entry, while the recycled material is backed by a built-in stainless-steel wire mesh, so others can't cut their way in. The Type-A design gives everything its place. Plus, the internal RFIDsafe pocket makes sure tech-savvy strangers don't get to shop on our dime.
