Detailed Reviews
1The tomtoc Navigator-T66 is a structured, carry-on travel backpack with a separate laptop compartment and lots of internal organization. tomtoc lists it at 20.47 x 12.99 x 9 inches, with usable capacity of about 38 to 40 liters depending on how you pack.
It is built for flights and cities, not trails: think airline cabin bag with good straps rather than a hiking pack. The fabric is PFAS-free, and the stiff sides hold their shape so packing cubes slide in and out easily.
Pros & Cons
What we like
- Dedicated laptop compartment
- Structured shape suits packing cubes
- PFAS-free materials
Watch out for
- Not built for hiking
- Heavier than soft travel packs
Key Specs
- Capacity: about 38-40 liters
- Size: 20.47 x 12.99 x 9 in (brand listing)
- Laptop: separate compartment
- Materials: PFAS-free
2The Farpoint 40 is one of the most recommended one-bag travel packs for good reason. It meets most carry-on size limits, opens wide like a suitcase, and has a real load-lifting frame with a men’s-specific harness.
WingJacket compression straps cinch the pack down when it is not full, a direct-zip 3-1-1 pocket keeps liquids ready for the security line, and front and bottle pockets handle quick-grab items. It is not cheap, but it carries better than most travel backpacks because it borrows its suspension from Osprey’s hiking packs.
Pros & Cons
What we like
- Suitcase-style opening
- Real frame and hip belt
- 3-1-1 liquids pocket for security
Watch out for
- Premium pricing
- Hip belt adds bulk in the overhead bin
Key Specs
- Capacity: 40 liters
- Fit: men’s-specific
- Frame: load-lifting
- Compression: WingJacket
- Carry-on: meets most limits (check your airline)
3The Daylite Carry-On 44 squeezes the most volume out of a carry-on footprint. Osprey says it meets most airline carry-on limits when compressed, and it opens clamshell-style with lockable zippers.
A padded laptop sleeve and an external toiletry pocket keep security checks fast, and the ventilated back panel is a real upgrade over flat-backed luggage-style bags. It is a smart pick for travelers who want maximum room without paying checked-bag fees, as long as you compress it before you fly.
Pros & Cons
What we like
- 44 liters in a carry-on footprint
- Lockable zippers
- Padded laptop sleeve
Watch out for
- Must be compressed to meet limits
- Minimal hip belt
Key Specs
- Capacity: 44 liters
- Opening: full-zip clamshell
- Laptop: padded sleeve
- Security: lockable zippers
- Toiletries: external pocket
4Tolaccea’s expandable travel backpack is a value pick for people who travel with a laptop. The 15.6-inch laptop compartment is suspended off the bottom to soften knocks, and it opens from the side so you can grab the laptop without opening the main compartment.
It works as a carry-on, a work bag and a duffel-style weekender. The expansion zip adds room for souvenirs on the way home, though a fully expanded bag may no longer meet stricter carry-on limits.
Pros & Cons
What we like
- Suspended laptop sleeve
- Side access to laptop
- Expands for the return trip
Watch out for
- Expanded size may exceed carry-on rules
- Bulky for daily commuting
Key Specs
- Capacity: 40-50 liters (expandable)
- Laptop: up to 15.6 in, suspended
- Access: side laptop zip
- Use: carry-on, work, weekend
5The Thule Landmark 40L is a carry-on adventure travel pack with security features for cities and transit. A hidden CashStash pocket under the SafeZone holds a passport and cash, and LoopLocks secure zipper pulls to deter pickpockets.
It also fits a 15-inch MacBook and a 12.9-inch tablet. It is a strong choice for international trips where theft protection matters as much as capacity.
Pros & Cons
What we like
- Hidden passport and cash pocket
- LoopLocks deter pickpockets
- Laptop and tablet storage
Watch out for
- Premium pricing
- Heavier than ultralight packs
Key Specs
- Capacity: 40 liters
- Security: CashStash, LoopLocks
- Laptop: 15 in MacBook
- Tablet: 12.9 in
6MATEIN’s carry-on backpack is one of the most widely bought budget travel bags on Amazon. Unzip the expansion panel and it grows to about 45 liters, enough for packing cubes, a toiletry kit and a camera bag.
Unexpanded, it is designed to fit standard overhead bins. It is a soft, simple travel bag, so it suits occasional travelers and weekenders more than people who walk all day with a full load.
Pros & Cons
What we like
- Expands to about 45 liters
- Low cost
- Plenty of organizer pockets
Watch out for
- No frame or real hip belt
- Expanded size can exceed limits
Key Specs
- Capacity: up to about 45 liters expanded
- Design: expandable carry-on
- Use: weekend and occasional travel

How to Choose a 40L Travel Backpack
A 40L travel backpack is the classic one-bag size. It holds a week or more of clothes and usually still fits within carry-on limits, so you skip checked-bag fees and baggage-claim waits.
- Carry-on size. Many US airlines allow carry-on bags around 22 x 14 x 9 inches, but international and budget carriers are often stricter. Always check your airline before you fly.
- Clamshell opening. A zip that opens the bag like a suitcase makes packing and finding items much easier than a top-loader.
- Compression. Straps that cinch a half-full bag keep it inside size limits and stop contents from shifting.
- Laptop sleeve. A separate sleeve speeds up security screening and protects your device.
- Harness. Padded straps, a sternum strap and a hip belt make a big difference when you walk from the station to your hotel.
- Security. Lockable zippers and hidden pockets help in crowded places.
Packing cubes turn a 40L bag into a tidy, easy-to-unpack system. Roll clothes rather than fold them, and wear your bulkiest shoes and jacket on travel days.
Choosing a 40L Backpack with a Laptop Compartment
A dedicated laptop compartment protects your computer and speeds up security screening. Not all laptop sleeves are equal.
- Size. Check the maximum laptop size, usually 15.6, 16 or 17 inches. Measure your laptop, not just the screen.
- Suspension. A sleeve that stops above the bottom of the bag protects your laptop when you drop the pack. Tolaccea’s suspended sleeve is a good example.
- Access. Separate or side access lets you pull out the laptop without opening the main compartment.
- Padding. Thick foam on both sides of the sleeve protects against knocks in overhead bins.
For daily commuting with occasional travel, a smaller pack with a laptop sleeve is enough. For one-bag trips with a laptop, choose a 40L travel pack like the tomtoc Navigator or Osprey Farpoint.

Frequently Asked Questions
Is a 40L backpack carry-on size?
Many 40L travel packs are designed around common carry-on limits of about 22 x 14 x 9 inches, but airlines differ. Check the listed dimensions and your airline’s rules, and compress the pack before you fly.
How many days of travel can a 40L backpack hold?
With packing cubes and quick-dry clothes, most people fit five to seven days of clothes in 40 liters, which works for longer trips if you do laundry along the way.
Can I fit a laptop in a 40L hiking backpack?
Usually in the hydration sleeve, but it will not be well protected. If you travel with a laptop, choose a travel pack with a padded laptop compartment.
What is the best backpack size for international travel?
Most international travelers do well with 35 to 40 liters, which fits many international carry-on limits when compressed. Check weight limits, too.
Do wheeled backpacks count as carry-on?
Many are designed to fit carry-on limits, but wheels and handles add size and weight. Check the dimensions and weight against your airline’s rules.
Final Verdict
The Osprey Farpoint 40 is the best all-round 40L travel backpack, and the tomtoc Navigator-T66 is the best structured, laptop-friendly option. The MATEIN is the low-cost pick for occasional trips.
