You may already know that you want a small crossbody or sling for travel. The harder part is finding one that is actually small enough for your passport, phone and wallet without giving up the feature you care about most.
Recent travel discussions show buyers looking for exactly that: compact bags that stay close to the body, sometimes under a jacket, instead of the much larger slings that often appear in search results. [1] [2]
If this small crossbody is only for your valuables and you still need one main carry-on for clothing or formalwear, our 2-in-1 garment duffel bag guide compares four larger carry-on options for that separate job.
Need the best balance of slim size and useful storage? Start with the Concept Global Travel Sling Bag 2.0 Mini.
Want the bag hidden under a jacket? The Pacsafe GO Tech is the more focused option.
Security matters more than concealment? Look more closely at the Travelon Metro.
Trying to spend less? The tomtoc T32 gives you more usable room for less money.

Need More Than a Passport Wallet Without Carrying a Bulky Sling?

This is where the Concept Global Travel Sling Bag 2.0 Mini becomes relevant. Concept Global says the Mini is sized for a phone, passport, keys, charging cables and a power bank. [4]
The 2.0 also lists YKK zippers, RFID-blocking material, a hidden rear pocket, a reinforced strap and a locking buckle. [4] The practical reason to consider it is the combination of more usable storage than a document pouch with a relatively thin 1.2-inch profile.
Look elsewhere when: lower price matters more than the extra security hardware.

Want the Bag to Stay Discreet Under a Jacket?
$59.95
If concealment matters more than capacity, the Pacsafe GO Anti-Theft Tech Crossbody is the more focused choice. Pacsafe specifically describes it as a slim organizer that can be hidden discreetly under a jacket. [3]
It is designed around a passport, cards, cash and phone, with RFID protection, a reinforced strap and secure zipper hardware. [3] The trade-off is limited spare capacity.
Look elsewhere when: you need room for several electronics or larger accessories.
Is Stronger Anti-Theft Construction Your Main Priority?
$55
The Travelon Metro Convertible makes more sense when theft protection matters more than having the thinnest possible bag. Travelon lists slash-resistant body panels, a reinforced lock-down strap, locking compartments and RFID organization. [5]
Its 1L capacity gives you more usable space than a passport organizer, while the two-inch depth makes it more structured. That is the trade-off: stronger physical security, but less discreet carry.
Look elsewhere when: under-jacket concealment matters more.
Want More Space Without Paying for Premium Security Hardware?
$30.60 sale
At 1.5L, the tomtoc SlingBean-T32 provides more usable capacity than most options here while remaining under two inches deep. tomtoc lists space for a phone, passport, cards and small essentials, plus RFID lining and a hidden rear pocket. [6]
What it does not provide is the same slash-resistant or locking construction listed by Pacsafe and Travelon. That makes it more relevant when value and capacity matter more than maximum security hardware.
Look elsewhere when: reinforced physical security is your main requirement.
Would You Rather Have Simpler Everyday Access?
$45
The ALPAKA Flight Sling 1L takes the simpler route. It offers two zip compartments and a body-side rear pocket rather than a dedicated locking or slash-resistant system. [7]
That can matter if you reach for your phone regularly and do not want additional security hardware slowing normal access.
Look elsewhere when: lockable zippers and a reinforced strap are non-negotiable.
Do You Really Carry Only the Basics?
$26.95 sale
The Travelon Courier Mini is only 0.5L and is built around passport and card storage plus room for a phone and keys. Travelon also lists RFID organization, locking compartments and slash-resistant construction. [8]
Its limitation is also its purpose: there is very little spare room.
Look elsewhere when: you also carry a power bank, sunglasses or larger accessories.
Which Direction Makes the Most Sense for You?
Need the broadest balance: Concept Global Mini gives you useful storage without moving into bulky-sling territory.
Concealment matters most: Pacsafe GO Tech sacrifices capacity to stay flatter.
Physical security matters most: Travelon Metro adds more reinforced anti-theft construction.
Budget matters most: tomtoc T32 gives you more usable space for less money.
Easy access matters most: ALPAKA Flight Sling avoids dedicated locking hardware.
You carry almost nothing: Travelon Courier Mini keeps the bag close to the size of the actual load.
Before You Buy, Decide Which Trade-Off You Can Accept
A flatter bag usually gives you less space. Stronger anti-theft hardware can add structure and slower access. Lower-priced options may give up reinforced construction, while more capacity generally means more bulk.
That is why there is no universal winner here. The better choice is the bag whose compromise matches your priorities. If you are still unsure whether you need anti-theft hardware at all, our Anti-Theft Sling vs Regular Crossbody guide covers that question separately.
Bottom Line
For a passport, phone, keys and a small power bank without much bulk, Concept Global Mini is the strongest starting point. For true under-jacket carry, Pacsafe GO Tech is more focused. If stronger physical anti-theft construction matters most, Travelon Metro deserves a closer look.
The tomtoc T32 makes more sense when budget and capacity come first, ALPAKA suits buyers who want uncomplicated access, and Travelon Courier Mini fits travelers who genuinely carry little more than valuables.
Frequently Asked Questions
Is a 1L–1.5L crossbody bag big enough for a passport, phone and travel essentials?
For a light travel load, usually yes. Travelers discussing 1L–1.5L slings commonly mention carrying a passport, phone, wallet, keys and earbuds in this size range. A small power bank can also fit in some designs, but once you add larger chargers, sunglasses or other accessories, 1L can start feeling tight. [9]
If your carry is mostly passport, phone and wallet, a 1L bag may be enough. If you also want charging gear, around 1.5L gives you a little more flexibility.
If you started with a roomier Emmafy-style bag but now think that format is larger or more expensive than you need, our Emmafy dupes and alternatives guide compares other directions by size, organization and price.
Can you wear a small crossbody or sling bag under a jacket?
Yes, but the bag’s depth and how much you put inside matter more than the capacity number alone. Travelers specifically discuss using small 1L-class slings and compact crossbody bags under jackets for passports, phones and other valuables. [10]
A lightly packed slim bag will usually sit flatter than the same bag filled with a power bank and bulky accessories, so under-jacket carry should be treated as a fit question rather than a guarantee.
Are anti-theft sling bags actually worth it for travel?
They can be useful if pickpocketing is one of your main concerns, but the features are better viewed as extra barriers rather than theft-proof protection. Travelers commonly look for locking zippers, reinforced straps and hidden body-side pockets when choosing anti-theft bags. [11]
If you mainly want to keep your passport and phone close to your body, a simple crossbody may be enough. If you are unsure whether specialist security hardware is worth it, see our anti-theft sling vs regular crossbody guide. If physical security features are already a priority, compare the best anti-theft sling bags for Europe.
