Locking zippers, hidden zippers, and slash-resistant construction address different forms of opportunistic theft. None is automatically the best security feature for every traveler.

Quick Answer: Hidden zippers reduce easy access while the bag is worn. Locking zipper pulls add a mechanical delay. Slash-resistant materials make cutting the fabric or straps harder. For most city and travel users, protected zipper access and secure internal pockets provide the strongest everyday value, while slash-resistant construction is more specialized.
