Are you planning a backpacking trip across Europe? Headed onto the Appalachian Trail? You need a backpack that is going to protect all of your sensitive items -- including credit cards and identification. That's where the Pacsafe VentureSafe trail backpack can really help you. This backpack is made from a sturdy metal construction and fabric that is not only strong enough that a knife won't cut through it but blocks radio frequencies. Today's bag snatchers and pickpockets are advanced, and they use radio frequency technology to capture your information from far away. You won't have that problem with the Pacsafe VentureSafe bags. The backpack also features hidden pockets, anchored zippers and locks that prevent the person passing by to open your bag in any way.
