Anti-theft bags have exploded in popularity, with brands promising everything from slash-proof construction to RFID-blocking technology. But which features genuinely enhance security, and which are primarily marketing designed to justify higher prices? This comprehensive guide examines the most common anti-theft features, explaining how they work, when they're valuable, and when you might be paying for peace of mind rather than actual protection.
RFID-Blocking Technology
How It Works
RFID (Radio Frequency Identification) technology enables contactless payment and identification through chips embedded in credit cards, debit cards, and passports. These chips communicate with readers via radio waves. RFID-blocking materials contain a metallic layer (usually aluminium or copper-based) that creates a Faraday cage, preventing radio waves from reaching the chips inside.
The Real-World Threat
The fear: thieves with portable RFID scanners could steal your card information simply by standing near you in a crowd. The reality is more nuanced. While RFID skimming is technically possible, documented cases of this actually occurring in the wild are extremely rare. Most modern payment cards use encryption and dynamic codes that limit the usefulness of any intercepted data.
However, older RFID-enabled cards and some international passports may be more vulnerable. If you're travelling internationally with an RFID passport or carrying older cards, RFID protection provides genuine peace of mind.
Our Verdict on RFID Blocking
Worth it: For frequent international travellers, those with older cards, or anyone who simply values the peace of mind. The technology adds minimal cost and weight to bags.
Not essential: If you primarily use newer Australian cards with modern encryption and don't travel internationally frequently, RFID protection is a nice-to-have rather than a must-have.
Slash-Resistant Materials
How It Works
Slash-resistant bags incorporate materials that resist cutting. This typically involves wire mesh integrated into the fabric, chainmail-like structures, or specially engineered cut-resistant fibres similar to those used in protective gloves. The goal is to prevent thieves from quickly slicing open your bag to grab contents.
The Real-World Threat
Bag slashing does occur, particularly in certain high-tourism areas of Europe, South America, and Southeast Asia. Thieves use razor blades or sharp knives to quickly open bags, often in crowded situations where the victim doesn't immediately notice. The slash-and-grab technique relies on speed—the thief cuts, grabs visible items, and disappears before the victim realises what happened.
Effectiveness Assessment
Quality slash-resistant materials genuinely work. They won't stop a determined attacker with time and the right tools, but they effectively defeat the quick slash-and-grab technique that relies on speed. The wire mesh or cut-resistant fibres catch and resist the blade, buying you time to notice and react.
However, slash-resistance adds weight and can make bags stiffer. For everyday use in Australia, this protection may be overkill. For travel to high-risk areas, it's a worthwhile investment.
Our Verdict on Slash-Resistant Materials
Worth it: For international travel to destinations with known pickpocketing issues, particularly solo travellers or those visiting crowded tourist areas.
Not essential: For everyday Australian use or travel to low-risk destinations. The added weight and stiffness may not justify the protection for most users.
Slash-Resistant Straps
How It Works
Like slash-resistant body panels, these straps incorporate wire cable or cut-resistant materials within the strap itself. The fear is that a thief might cut your strap to steal the entire bag.
The Real-World Threat
Strap cutting is less common than bag slashing but does occur, particularly with bag-snatching from motorcycles in some Southeast Asian cities. A wire-reinforced strap makes the cut-and-run technique ineffective.
Important note: If someone aggressively tries to snatch your bag and the strap doesn't give way, you could be dragged or injured. Security experts sometimes debate whether an uncuttable strap is entirely beneficial—in a violent grab scenario, you might be better off losing the bag than being pulled down.
Locking Zippers
How They Work
Locking zipper systems come in several varieties:
- Interlocking pulls: Zipper pulls that clip together, requiring deliberate action to separate
- Tethered pulls: Pulls attached to the bag body, making them harder to grab and operate quickly
- Lockable pulls: Small loops that accept a padlock or cable lock
- Hidden zippers: Zippers positioned in non-obvious locations or covered by flaps
Effectiveness Assessment
Locking zippers genuinely deter opportunistic theft. Pickpockets rely on quickly and quietly opening your bag—anything that slows this process or makes it more noticeable significantly reduces risk. These systems won't stop a determined thief with time and tools, but they're highly effective against the casual brush-by pickpocket.
The downside: locking systems can also slow your own access. If you need to frequently retrieve items, the constant locking and unlocking becomes tedious. Consider your usage patterns before prioritising this feature.
Our Verdict on Locking Zippers
Worth it: For travel and any situation where you'll be in crowds with your bag accessible to others. One of the most practical anti-theft features available.
Consider carefully: If you need frequent access to your bag contents, the security benefit may not outweigh the inconvenience.
Hidden Pockets and Compartments
How They Work
Hidden pockets are exactly what they sound like—compartments that aren't immediately visible to someone examining your bag. Common locations include:
- The back panel (against your body)
- Inside main compartment flaps
- Beneath false bottoms
- Within structural elements like padded straps
Effectiveness Assessment
Hidden pockets are extremely effective because they work on the principle that thieves typically won't spend time thoroughly searching a bag—they grab visible valuables and run. Keeping your most important items (passport, primary cards, emergency cash) in a location that requires deliberate searching to find provides genuine protection.
This is one of the few anti-theft features that works equally well against sophisticated thieves and opportunistic pickpockets. Even if someone gets into your bag, they're likely to miss well-hidden compartments.
Security Attachment Points
How They Work
These are loops, rings, or cables that allow you to secure your bag to a fixed object—a chair leg, table, luggage trolley, or railing. Some bags include retractable cables; others simply provide attachment points for separate locks.
Effectiveness Assessment
Attachment points are valuable in specific scenarios: waiting at cafes, sleeping on overnight transport, or any situation where you might set your bag down and become distracted. They prevent the simple grab-and-run theft that accounts for many bag losses.
The limitation: carrying and deploying a lock adds hassle. Retractable cable systems built into bags are more convenient but add weight and can malfunction. This feature is most valuable for travellers who frequently find themselves in situations requiring temporary bag security.
What Really Matters: A Hierarchy of Security
Based on real-world effectiveness and practical considerations, here's how we'd prioritise anti-theft features:
- High value: Hidden compartments, locking/interlocking zippers, basic RFID blocking
- Situationally valuable: Slash-resistant materials and straps (for high-risk travel), security attachment points (for specific scenarios)
- Nice to have: Tethered components, padded RFID pockets, anti-theft design elements
Beyond Features: Behaviour Matters More
The most sophisticated anti-theft bag in the world won't protect you if you're careless. Good security habits trump fancy features:
- Keep your bag in front of you in crowded areas
- Don't flash expensive items when accessing your bag
- Stay aware of your surroundings, particularly in tourist areas
- Don't keep all valuables in one place
- Know the common scams and distraction techniques in your destination

Final Thought
Anti-theft features provide real value, but they're not magic shields. Think of them as layers in a security approach that includes awareness, behaviour, and smart item placement. The best anti-theft bag is one that makes you feel confident without making you complacent.
