How to Protect Valuables When Traveling
Almost every product in this category tries to make one bag harder to open. The technique that actually works is making no single loss matter.
We have not tested this gear. Every figure here is compiled from published manufacturer specifications and published airline policies, and the arithmetic is public so you can check it. This page contains affiliate links — see the affiliate disclosure.
Redundancy beats security. A second card in a different bag survives a theft that no lock prevents. And it matters more than product choice, because carriers publish exclusions for valuables, electronics, documents and jewelry from checked-baggage liability — so the bag was never insured in the first place.

Plan for loss, not for prevention
The security aisle sells prevention: harder zips, cut-resistant panels, locks. All of it is aimed at making one bag survive an attempt.
The trouble is that the failure you actually experience is rarely an attempt. It is a bag left in a taxi, a wallet gone from a table, a case that did not arrive. Prevention products address none of those, and the technique that addresses all of them costs nothing: make no single loss matter.
What to split, and where
| Item | Primary location | Backup location | Why |
|---|---|---|---|
| Payment cards | Wallet | A different bag entirely | Both cards in one wallet defeats the purpose of a backup |
| Cash | Wallet, small amount | The bottom of a packing cube | Enough for a taxi if the wallet is gone |
| Passport | On your person in transit | Photograph emailed to yourself | The copy is what an embassy works from |
| Phone | On you | Cloud backup, and a written note of key numbers | A dead phone is the same as a stolen one |
| House keys | Personal item | Someone at home has a set | Nothing recovers a key at 3,000 miles |
The card row is the one people get wrong most often. Two cards in the same wallet is one card for practical purposes. What a travel wallet should hold.
What carriers actually cover
Worth reading before deciding what goes in a checked bag, because the answer is published and it is narrower than most people assume.
Carriers publish exclusions from checked-baggage liability for valuables, electronics, documents, jewelry and similar categories. That exclusion is in the conditions of carriage you agreed to at booking, and it is not negotiable at a desk afterwards.
Which produces a simple rule with no exceptions worth making: never check anything you cannot replace. Not because it is likely to be lost, but because if it is, the loss is entirely yours. How a claim actually works.
The bag that cannot be taken from you
Everything on the do-not-lose list belongs in the personal item, and the reason is mechanical rather than about theft.
A carry-on can be gate-checked when the bins fill. A checked bag can miss a connection you made. The personal item fits under the seat and therefore stays with you from the door to the seat, every time. The full list for that bag.
Where products genuinely help
- A TSA-accepted lock on a checked bag. A real deterrent against casual pilferage, and it survives inspection rather than being cut off. Which lock, and why.
- Lockable zips on a day bag. Two pulls clipped together defeat the opportunist, which is the threat that actually happens in a crowd.
- A tracker in each checked bag. It prevents nothing and it turns “somewhere in the system” into a location you can state at a desk. The two compared.
- An RFID pocket, if you want one — a privacy feature for e-passports rather than an anti-fraud measure.
Note what is missing: a money belt. Worn under clothing it is genuinely secure and it is also unreachable, which means you take it off in public to use it — at which point you have shown everyone where your money is. A split-card strategy does the same job without the theatre.
The free version, which is most of it
- Photograph your passport data page and email it to yourself. Two minutes, and it is the single most useful thing on this page.
- Photograph your cards, front and back. You need the number to cancel one, and the number is on the card that is gone.
- Write down your bank’s international number somewhere that is not your phone.
- Wear the bag on your front in crowds. Unattractive and more effective than any product.
- Never hang a bag on the back of a chair. Every café theft story starts here.
- Photograph the packed checked bag before you close it. It is the evidence a contents claim is built on.
If it happens anyway
| Loss | First action | Then |
|---|---|---|
| Cards | Cancel from the backup phone or a borrowed one | Use the second card you put somewhere else |
| Passport | Report locally, then the nearest embassy | The photograph is what they work from |
| Checked bag | File before leaving the airport | Written reference number, then receipts as you go |
| Phone | Remote wipe from any browser | The written note of key numbers |
Every pick, with the working
Each entry below shows the published inputs, the four axis scores they produce, and what you give up. The order is the computed order, not a commercial one.
1 · A personal item that is also the daypack for the whole trip
Osprey Daylite Plus 20L Backpack
The only personal-item bag here with a published weight, a published price and a warranty that names no end date — $4 per covered year is the cheapest figure on this site.
- Published size
- 19 × 11 × 9.5 in
- Weight
- 1.31 lb
- Capacity
- 20 L
- Weight per liter
- 0.07 lb/L
- Cost per covered year
- $4/yr
- Published list price
- $80
Warranty All Mighty Guarantee — any reason, any product, any era
Fits No US carrier in our table publishes a limit these dimensions satisfy. See the limits.
What it does well
- $4.00 per covered year is the lowest cost-per-year figure in this ledger
- 1.31 lb for 20 L, and it is the bag you then use every day at the destination
- 19 × 11 × 9.5 in fits the published personal-item box at American, Southwest, Frontier and Allegiant
What you give up
- Over United's published 17 × 10 × 9 in limit on all three dimensions
- 20 L is genuinely small — this is a day bag, not a week's clothes
- No lockable zippers
The arithmetic behind the score
- Value 8.3/10 — $80 ÷ 20 yr = $4/yr; $80 ÷ 20 L = $4/L
- Airline-fit breadth 0.0/10 — Fits the published personal-item limit at 0 of 8 US carriers
- Carry efficiency 9.4/10 — 1.31 lb ÷ 20 L = 0.066 lb/L
- Warranty & support 10.0/10 — no stated end date (6 of 6); repair published (+2); covers airline damage (+2)
Weights and breakpoints are published on how we rank. Where an input is not published, that axis is dropped and the remaining weights are re-normalized.

2 · International trips with paperwork to fill in
Bellroy Travel Wallet (RFID)
79 g holding a passport, seven card slots, cash and a micro pen — the pen is the detail, because landing cards still exist and nobody ever has one.

- 79 g published for passport, cards, cash and a pen in one object
- Published RFID protection on the card slots
What you give up
- Bellroy publishes that it does not fit Irish or pre-2017 German passports
- One passport only, so it is the wrong object for a family
- No manufacturer-published US price
The arithmetic behind the score
- Value not scored — No manufacturer-published price, so this axis is not scored.
- Airline-fit breadth 10.0/10 — Fits the published carry-on limit at 11 of 11 US carriers: AA, DL, UA, WN, AS, B6, F9, G4, HA, MX, SY

3 · Two passports in a pocket-sized cover

Warranty 3 year warranty covering material and workmanship defects
Fits 11 of 11 US carriers: AA, DL, UA, WN, AS, B6, F9, G4, HA, MX, SY. See the limits.
What it does well
- Published to hold one to two passports — most covers hold one
- 78 g and 0.75 in thick, so it fits a jacket pocket
- Magnetic closure rather than a zip, which is faster at a desk
What you give up
- Fewer card slots than the Travel Wallet
- Leather is the wrong material if it will get wet
- No manufacturer-published US price
The arithmetic behind the score
- Value not scored — No manufacturer-published price, so this axis is not scored.

4 · Zipper pulls on a soft case, where a rigid shackle will not reach
Master Lock 4688D TSA-Accepted Combination Luggage Lock
A set-your-own three-digit combination and a braided cable shackle, recognized as a TSA-accepted lock in a published 29 countries — which is the only specification that decides whether a screener cuts it off.

Warranty No warranty term published on the product page
Fits No published dimensions to check.
What it does well
- TSA-accepted in a published 29 countries, so a screener opens and relocks rather than cutting
- Flexible braided steel shackle reaches zipper pulls a rigid shackle cannot
- Set-your-own combination means nothing to lose in a hotel room
What you give up
- No warranty term published on the product page
- No published price, so cost per covered year cannot be computed
- A TSA lock is by design openable with a master key — it deters, it does not secure
The arithmetic behind the score
- Value not scored — No manufacturer-published price, so this axis is not scored.
- Airline-fit breadth not scored — No published dimensions to check against carrier limits.
- Carry efficiency not scored — No published capacity, so weight per liter cannot be computed.
- Warranty & support 0.0/10 — no published term (0 of 6); no published repair route (+0); airline damage not covered (+0)
Weights and breakpoints are published on how we rank. Where an input is not published, that axis is dropped and the remaining weights are re-normalized.
Specs: Master Lock published specifications, compiled 3 September 2026. Master Lock publishes component dimensions rather than a bounding box: a 1 3/16 in (30 mm) wide body with a 1/8 in (3 mm) diameter, 1-1/2 in (38 mm) long flexible braided steel shackle. Master Lock publishes no list price for the 4688D on its own product page. The Value axis is not scored for this lock.
5 · Crowded cities where the bag is on your back and behind you
Pacsafe Metrosafe LS350 Anti-Theft Backpack (15 L)
Skip this one. Skip it as your valuables strategy. Lockable zippers are a genuine feature and they are still one bag - and a strategy built on one bag being hard to open fails completely the moment that bag is gone. Buy it for the daily commute through a crowd, not as the plan.
15 L with lockable zippers and a padded 13 in laptop sleeve — the anti-theft features are published, and almost nothing else is.

What it does well
- Lockable exterior zippers, which is the feature that actually stops an opportunist
- Published 13 in padded laptop sleeve inside a 15 L bag
- RFID-blocking interior pocket published as standard
What you give up
- No manufacturer-published weight, dimensions, price or warranty term we could read
- 15 L is a day bag — it is not a carry-on and will not hold a trip
- Four of our four axes are unscorable or near it, which is a real cost
The arithmetic behind the score

- Airline-fit breadth not scored — No published dimensions to check against carrier limits.
