Contents of a backpack are susceptible to pickpocketing for two reasons: A backpack is more comfortable carried on the back; and it is easy for traditional zippers to be unzipped quickly without anyone noticing. Travel Anti-Theft Zipper is a modified traditional zipper that will deter pickpocketing. Two magnetised pieces are added to the zipper pull-tabs so that the tabs automatically attract each other and snap shut. This means that unzipping the bag will have to take some time and effort. This extra time gained may be the difference needed to catch the thief in action.
