“Anti-theft” is not a regulated term, and that is the entire reason this question is hard to answer. It is printed on $25 commuter backpacks and on $250 travel packs, and the two products have almost nothing in common. So before deciding whether it is worth the money, it is worth knowing exactly what you would be buying — because on the cheap end you are usually paying for a pocket, and on the expensive end you are paying for a laminated steel mesh.
The short version: locking zippers are worth it on almost any bag you will carry in a crowd, slash-resistant construction is worth it for a minority of trips, and a hidden pocket is a nice touch that should not cost you anything extra. The rest of this guide is how to tell them apart on a listing, and what each one genuinely prevents.
The four features, and what each one stops
1. A concealed back pocket.A zip pocket on the face of the bag that sits flat against your spine when you are wearing it, so it cannot be reached while the bag is on. It is a genuinely useful place for a passport or a phone and it costs the maker almost nothing, which is why it appears on budget bags like the MATEIN and LOVEVOOK laptop packs. What it does not do is protect the bag — everything in the main compartment is as accessible as it was before. Treat this as organization with a security flavour.
2. Locking or clipping zippers. Zipper pulls that clip to a hidden anchor or take a small lock, so the main compartment cannot be slid open silently behind you. This is the first feature on the list that actually changes outcomes, and the mechanism is time: the theft it prevents is the two-second one, done by someone walking past a bag on a shoulder or a chair back. Make it a ten-second job that requires both hands and attention and it stops being worth doing. For the money, this is the single best feature on this page.
3. RFID-blocking pockets.A lined pocket that blocks the radio read of a contactless card or a passport chip. It does what it says. Whether it matters is a different question — scanning fraud in a crowd is uncommon and card networks cover fraudulent charges — so the honest framing is that RFID lining is a reasonable inclusion on a bag you want anyway, not a reason to spend more. Pacsafe includes it; so does Travelon, at a third of the price.
4. Slash-resistant construction. A wire or composite mesh laminated into the fabric panels, and often into the shoulder straps so the bag cannot be cut off you. Pacsafe publishes this for the Metrosafe X as an eXomesh slashguard over a 750D recycled polyester shell. This is the only feature here that is engineering rather than design, it is what makes a bag genuinely hard to get into, and it is also where the weight and the money go. The Metrosafe X is 1.87 lb for 20 liters, which is heavy for a daypack precisely because of this.
So when is it worth it?
Three honest tiers, which is also how we rank the anti-theft roundup:
- Short trips, low-risk destinations, a day bag you keep in sight. Not worth paying a premium for. Buy the bag you actually want and put your passport in a concealed pocket if it has one. A cheap bag with a hidden pocket and lockable main zippers covers this entirely.
- City travel, crowded transit, markets, night trains. Worth it, at the middle tier. Locking hardware and an RFID pouch at mid-market money is the best value-for-anxiety trade on this page: it removes the opportunistic theft that accounts for most of what actually happens to travelers.
- Months away, irreplaceable equipment, or a documented high-risk route. Worth it at the top tier. If the bag being opened or cut would end the trip rather than annoy you, buy the slash-resistant construction and carry the extra pound.
And the case where it is not worth it at any price: if you are buying it instead of changing how you carry the bag. Wearing a daypack on your front in a crowd, never hanging it on the back of a chair, and splitting your cards and cash between two places do more than any feature here. No maker worth trusting claims otherwise.
What to check on the listing before you pay for it
- Does it name the mechanism, or just the category?“Anti-theft design” is marketing. “eXomesh slashguard”, “locking zipper pulls”, “RFID-blocking pocket” are features. If a listing uses the first kind of language and none of the second, it has a hidden pocket.
- Are the straps protected too? Slash resistance in the panels and plain webbing on the shoulders means the bag can still be cut off you. The better packs laminate the straps as well, and say so.
- What does the weight tell you? Real slash-resistant mesh is heavy. A 20L bag at well under a pound and a half is not carrying a laminated panel, whatever the listing says.
- Is it a day bag or a main bag? Nearly all anti-theft bags are 20L daypacks. If you want the security on the bag that holds your clothes, that is a much shorter list and a much higher price.
- Is there a warranty?Security hardware is hardware, and hardware fails. Pacsafe publishes a 5-year limited warranty; most budget anti-theft bags publish no term at all, which we print as “Not published” rather than guessing.
Three bags, one per tier
Having set out what to look for, here is what each tier looks like in practice. Prices come from the live price layer with the date they were read.
#1Tier three: genuine slash-resistant construction, 1.87 lb, 5-year warranty
Pacsafe Metrosafe X 20L Anti-Theft Backpack
The real anti-theft pick — not a hidden pocket, but a system: slash-resistant fabric, locking zippers and RFID-blocking pockets. A 20L daypack for pickpocket-heavy cities where you want to stop worrying about your bag. Priced accordingly.
Strengths
- +Slash-resistant paneling and lockable zipper pulls — actual security, not just a hidden pocket
- +RFID-blocking pockets for cards and passport
- +Comfortable, low-key 20L daypack
Trade-offs
- −Security hardware adds weight and cost versus a plain daypack
- −20L is a day bag, not a travel main-bag
| Capacity | 20 L |

Fit note. This is what 'anti-theft' should mean: slash-resistant fabric and locking zippers, not a marketing sticker. Overkill for a quiet trip; exactly right for a crowded market or a night train.
Specs read from the product listing, on September 7, 2026. “Not published” means the maker does not state that figure.
#2Tier two: locking hardware and RFID at a third of the price
Travelon Anti-Theft Metro Backpack
The sensible middle of the anti-theft market: real locking hardware and an RFID-blocking pouch at roughly a third of a Pacsafe's price. You give up the full slash-resistant paneling, so treat it as strong deterrence rather than a vault — which, for most trips, is the honest amount of security to buy.
Strengths
- +Locking hardware and an RFID-blocking pouch at a mid-market price
- +Low-key everyday styling that doesn't read as a tourist bag
- +Light enough to work as a personal item or day bag
Trade-offs
- −Deterrent-grade, not the full slash-resistant system a Pacsafe gives you
- −A day bag — it is not a one-bag main travel pack
| Capacity | Not published |

|---|
Fit note. Anti-theft is a spectrum, not a yes/no. This sits in the middle: locking zippers and RFID shielding stop the opportunist, while a determined thief with a blade is the Pacsafe's problem to solve. Most travelers only ever need the middle.

#3Tier one: a hidden back pocket and lockable zippers, cheaply
MATEIN Travel Laptop Backpack (Anti-Theft)
One of Amazon's best-selling laptop backpacks for a reason: it's a cheap, sensible personal-item bag with a hidden back pocket, a USB pass-through and a luggage sleeve. Not a travel 'system,' just a reliable day-and-commute bag that flies well as your second item.
Strengths
- +Hidden anti-theft back pocket and lockable main zippers
- +USB pass-through and a padded 15.6" laptop sleeve
- +Luggage strap sleeve to stack it on a roller
Trade-offs
- −A commuter bag, not a one-bag travel pack
- −Budget materials — functional, not premium

Fit note. 'Anti-theft' here means a concealed back pocket and lockable zippers — real deterrents for a day bag, not a slash-proof security pack. As a cheap personal item it's hard to beat.

The Metrosafe X is the bag to buy if you have decided the risk is real: Pacsafe publishes the construction, the dimensions and the warranty, and at 17.7 x 11.8 x 5.1 in it doubles as a personal item on a flight. The Travelon is the one most travelers should actually buy — real locking hardware and an RFID pouch, low-key styling, and the honest admission that it is strong deterrence rather than a vault. The MATEIN is the floor: a concealed pocket, lockable main zippers, a USB pass-through and a luggage sleeve on a cheap commuter bag. That is “anti-theft” in its weakest true sense, and at its price that is a fair deal rather than a con.
If you want the security on your main bag rather than a daypack, the Pacsafe Venturesafe EXP35 is the one pack we cover that does it — a full 35L travel bag with the same construction. It is also the most expensive way to buy 35 liters, which is the trade-off stated plainly on best 35L travel backpacks.
The part a bag cannot do
Every honest version of this answer ends the same way. The bag removes the easy opportunity and buys you seconds; it does not make you unrobbable, and the features that sound most dramatic are not the ones that prevent the most incidents. Locking zippers and a bag worn on your front in a crowd will do more for you than a slash-proof panel on a bag hanging off one shoulder.
If you have decided to buy one, the anti-theft travel backpacks roundup ranks the field at all three tiers, and how to lock a backpack covers getting the locking part right on a bag you already own, which costs almost nothing. We own none of these bags and have tested none of them; our method and its limits are in how we choose.
