Pickpockets do not pick locks. They wait for a crowded metro door, take the thing that opens easily, and are three carriages away before you feel lighter. A good anti-theft backpack does not make you a hard target so much as an annoying one, and annoying is usually enough.
The phrase “anti-theft” covers everything from a zip that faces your spine to a bag with steel mesh woven through the fabric, and the gap between those two is enormous. What follows sorts that out, then matches it to how people actually travel: a commuter on a busy line, a backpacker in hostels, someone flying with a laptop under the seat in front.
At a glance
How to choose an anti-theft backpack
Know which threat you are buying against
There are three, and they need different answers. The opportunist unzips a pocket while you look at a departure board; hidden zips and a lock defeat that entirely. The slasher cuts the bag or the strap and walks off with the contents or the whole bag; only slash-resistant fabric and straps stop that, and almost no budget bag has them. The determined thief with time and privacy will get in regardless, which is why nothing here is a safe. Be clear about where you are going. Most travelers face the first threat constantly and the second rarely.
Hidden zips and back pockets do most of the work
The cheapest feature is also the most effective. A pocket that sits flat against your spine cannot be opened while you are wearing the bag, full stop. Concealed zips under a flap slow a hand down long enough to be noticed. Put your passport, phone and cards there and the rest of the bag becomes a container of clothes that nobody wants. This costs nothing and it is why a well-designed budget bag can outperform a careless expensive one.
Locks are a deterrent, not a vault
A combination lock on the main zip means a thief must stand there working at your bag rather than making one movement. That is the entire point, and it is a good one. It will not survive a knife or a determined pull. A TSA-approved lock adds the separate benefit that security staff can open it with a master key instead of cutting it off, which matters if the bag goes in the hold. Set the combination to something that is not the factory default, which is the mistake nearly everybody makes.
Slash resistance is the real dividing line
This is what you pay the premium for. Slash-resistant construction weaves a wire or synthetic mesh through the panels and the straps, so a blade drawn across the bag does not open it and a strap cut does not drop it. Combined with locking compartments and lock-down hardware that fixes the bag to a chair leg, it changes the category of protection rather than the degree. If you travel through places where bag slashing is a known local technique, this is not optional; if you commute in a quiet city, it may be more than you need.
RFID pockets: useful, and oversold
RFID-blocking slots line a pocket with material that stops a reader scanning a contactless card or a passport chip through the fabric. The technology works. The threat is rarer than the marketing implies, since modern payment cards use one-time tokens rather than handing over reusable numbers, and a card skimmed at range is far less useful than a card taken. Take RFID slots as a sensible free extra on a bag you are buying anyway, and as a reason to keep your passport in a defined place, rather than the deciding feature.
USB ports charge nothing by themselves
A USB port on the outside of a bag is a pass-through: a cable runs to a power bank you put inside and supply yourself. None of these bags include a battery, and any listing implying otherwise is being loose with the truth. It is genuinely convenient, since it means charging your phone without opening the bag on a platform, which is itself a small security win. Just know what you are getting.
Size, and the personal item question
Airlines have made bag dimensions a sport. A bag around 18 by 12 by 8 inches generally passes as a personal item and fits under the seat, which for many trips means never paying for a carry-on. Larger 20-liter-plus bags buy capacity and lose that flexibility. Check the volume as well as the outside measurements: a bag can be personal-item sized and still swallow a laptop, a change of clothes and a lunch.
SHRRADOO Anti Theft Laptop Backpack with Combination Lock
The most popular shape in the category, and the reason is that it does the airport well for very little money. It unfolds 90 to 180 degrees flat, which is the detail that gets you through a security line without unpacking, and the separate laptop compartment swallows up to a 17-inch machine with a shockproof belt to stop it sliding. A password lock guards the computer compartment, a luggage strap slides it over a suitcase handle, and an external cable port handles phone charging. Mesh shoulder straps, a foam back panel and a chest strap keep it bearable when full.
- Pros: Cheapest here by a margin; combination lock included; fits laptops up to 17 in; opens flat for airport security; internal shockproof belt for laptop and tablet; luggage strap and chest strap; external charging port; one-year defect replacement; breathable mesh straps and back.
- Cons: No slash-resistant fabric, so it defends against opportunists rather than blades; the lock covers the computer compartment rather than everything; large enough that it may not pass as a personal item.
Best for: Students, commuters and anyone flying with a big laptop who wants a lock without spending much.
MATEIN Travel Laptop Backpack
Built to a measurement rather than a vibe: 18 by 12 by 7.8 inches, which is personal item size on most airlines and fits under the seat in front. That single fact can pay for the bag several times over on a budget carrier. Security here is the quiet kind, a hidden anti-theft pocket against your back for passport and phone, rather than a lock. It takes a 15.6-inch laptop in its own compartment, organizes the rest across a front panel of pockets with a key fob hook, and is made from water-resistant polyester with metal zips. A multi-layer ventilated back panel keeps it comfortable on long days.
- Pros: Confirmed personal item dimensions that fit under most airline seats; hidden back pocket for valuables; separate 15.6 in laptop compartment; water-resistant polyester with metal zippers; luggage strap for a suitcase handle; well-organized front pockets; thick ventilated back padding.
- Cons: No lock at all; no slash resistance; slimmer than the SHRRADOO, so a heavy packer will run out of room.
Best for: Flying light on budget airlines, and daily commuting where discretion beats hardware.
oscaurt Anti Theft Backpack with Hidden Zipper
The middle ground, and the cheapest bag here that says anything about cut resistance. Its fabric is described as anti-scratch and anti-cut, the main pocket uses hidden zippers, and there is a secret pocket at the back, so all three of the standard defenses are present in one bag without a premium price. A built-in cable and external USB port handle charging, the laptop sleeve takes 15.6 inches with an elastic band and velvet lining, and reflective strips on the front are a genuine safety feature for walking home after dark. Widened curved straps and an EVA back section carry the load.
- Pros: Cut-resistant fabric at a mid-range price; hidden zippers on the main pocket plus a secret back pocket; reflective strips for night visibility; USB port with internal cable; padded 15.6 in laptop sleeve with elastic retention; luggage strap; EVA ventilated back.
- Cons: Cut resistance is not the same as the woven slash-proof panels on the Travelon; no lock; power bank not included, as with every USB bag here.
Best for: Travelers who want a bit of everything, and cyclists or walkers who value the reflective panels.
Travelon Anti-Theft Classic Large Backpack
This is the one that takes the category name literally. A patented security system runs through the whole bag: a slash-resistant body, slash-resistant adjustable straps, locking compartments, and RFID-protected pockets for cards and passports. The 20-liter main compartment locks and holds a 15-inch laptop in a padded sleeve, while a fleece-lined rear compartment takes up to a 17-inch machine. The front compartment carries RFID slots, a phone pocket and a tethered key clip, so keys stop disappearing. It weighs two pounds, measures 11.75 by 18 by 7 inches, and uses air-mesh straps and back panel with a rear trolley strap.
- Pros: Genuine slash-resistant body and straps, the real dividing line in this category; locking compartments throughout; RFID-protected slots for passports and cards; two laptop sleeves, up to 15 in and 17 in; tethered key clip; 20 L capacity at only 2 lbs; air-mesh back and trolley strap.
- Cons: Premium price; no USB pass-through port; at 20 L and 18 in tall it is a carry-on rather than a discreet personal item.
Best for: City travel where bag slashing is a known risk, and anyone carrying a passport and a laptop through crowds.
BANGE Men’s Anti-Theft Backpack
Two locks, which is unusual. A zinc alloy combination lock guards the bag, and a separate TSA lock protects the middle pocket, meaning airport security can open that compartment with a master key rather than cutting it. The three-pocket layout is the other draw: a front pocket sized for a pair of shoes, the TSA-locked middle section for valuables, and a shockproof, water-resistant compartment for laptops up to 17.3 inches. Waterproof YKK zips sit on water-resistant Oxford fabric, and a USB 3.0 port on the outside handles fast charging from your own power bank.
- Pros: Zinc alloy combination lock plus a separate TSA lock; three genuinely separated compartments including a shoe pocket; fits laptops up to 17.3 in with shockproof padding; waterproof YKK zips over water-resistant Oxford; USB 3.0 fast charging port; breathable mesh back and straps.
- Cons: Most expensive here; no slash-resistant panels despite the price; power bank not included; the shoe compartment is dead space if you never use it.
Best for: Business trips and weekend getaways with a large laptop, gym kit and a wish to lock things properly.
The verdict
Best overall: the SHRRADOO anti theft laptop backpack. It is the most widely bought bag of this group and it earns that: a combination lock, a 17-inch laptop compartment with a retention belt, a flat 180-degree opening for security lines, a luggage strap and a charging port, at the lowest price here. For the opportunist threat that most travelers actually meet, it covers the ground.
Best value: the MATEIN travel laptop backpack. Personal item dimensions plus a hidden back pocket is a quietly excellent combination, and if it saves one carry-on fee it has paid for itself. The oscaurt is the step up if you want cut-resistant fabric without premium money.
Best premium: the Travelon Anti-Theft Classic Large. It is the only bag here with slash-resistant panels and straps alongside locking compartments, which is a different class of protection rather than a better version of the same one. Choose the BANGE instead if you want twin locks, a bigger laptop and a shoe compartment.
Frequently asked questions
Does an anti-theft backpack actually stop theft?
It stops casual theft, which is most theft. Hidden zips, a back pocket and a lock all work by making your bag slower and more conspicuous to open than the bag next to it. None of them defeats a thief with time, privacy and a blade, and no bag here claims to. Combine the bag with habits: valuables against your spine, bag on your front in crowds, nothing important in an outer pocket.
Are these bags allowed through airport security?
Yes. Locks are fine, though you may be asked to open them. A TSA-approved lock lets screeners open the compartment with a master key rather than cutting it, which matters for checked bags. A bag that opens flat to 180 degrees also lets many airports scan the laptop without you removing it, which speeds up the line.
Do I need the USB charging port?
Only if you already carry a power bank, because none of these bags include one. The port is a pass-through: your battery goes inside, the cable runs to a socket on the outside. The real benefit is charging without unzipping your bag in a crowd, which is a small security gain on top of the convenience.
Is RFID blocking worth paying extra for?
It is worth having and rarely worth choosing a bag over. Contactless cards issue one-time codes rather than reusable numbers, so a scanned card is far less valuable than a stolen one. Passport chips are a more reasonable concern. Where RFID slots come as part of a bag you already want, use them and think no more about it.
What size should I get for flying?
If you want to avoid carry-on fees, look for roughly 18 by 12 by 8 inches and confirm against your airline’s personal item rules, since they differ and change. If you are checking a case anyway and just want a day bag at the destination, capacity and comfort matter more than the tape measure.
