Stop the unwanted tampering of your backpack whether by downtown baddies, airport pilferers, or worldwide opportunists when you utilize the award-winning Pacsafe Backpack & Protector. The patented Smart eXomesh cage system can't be easily cut since it is made of an adjustable high-tensile stainless steel locking device. Padlock included. Airport approved but you will still need to remove the mesh while going through security and then attach it when security has approved you to. Make sure there are no straps flopping around, so that it doesn't get caught in airport conveyor belts.
