There was no way to protect your camera bag from being easily opened and tampered with. The Gary Fong GearGuard Camera Bag Lock, Set of 2 (Large) allows you to lock your bag shut. The protective case keeps the clasp from being opened, thereby creating a deterrent to getting inside. You can lock with any small padlock, or secure the locked bag via cable to a solid post to deter thieves from taking the whole bag.
