Detailed Reviews
1The 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)
2The Fairview 40 is the women’s version of the Farpoint 40, with the same carry-on-friendly shape and suitcase-style opening but a harness and hip belt shaped for a women’s torso, shoulders and hips.
That fit is the whole point. Straps that curve around the chest and a hip belt angled for wider hips put weight where it belongs, which matters on long walks between stations or across old-town cobbles. It also gets WingJacket compression, a 3-1-1 liquids pocket and quick-access front pockets.
Pros & Cons
What we like
- Women’s-specific straps and hip belt
- Opens fully like a suitcase
- Carry-on friendly size
Watch out for
- Premium pricing
- Fewer internal organizer pockets than tech bags
Key Specs
- Capacity: 40 liters
- Fit: women’s-specific
- Frame: load-lifting
- Compression: WingJacket
- Liquids: direct-zip 3-1-1 pocket
3The 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
4The 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
5If 44 liters is more than you need, the Daylite Carry-On 35 trims the size for weekend trips and frequent short flights while keeping a padded, TSA-friendly laptop compartment that fits most 16-inch machines.
The AirScape mesh back panel breathes better than most travel bags, and up-specced fabrics keep weight down. It is a good fit for business travelers and anyone flying airlines with tighter carry-on rules.
Pros & Cons
What we like
- Fits most 16-inch laptops
- Breathable AirScape back panel
- Light for daily flying
Watch out for
- Below 40L for longer trips
- Simple organization
Key Specs
- Capacity: 35 liters
- Laptop: padded sleeve, most 16-inch models
- Back panel: AirScape mesh
- Use: weekend and business travel
6The LOVEVOOK 40L comes with three packing cubes, so it is ready for a trip out of the box. LOVEVOOK lists it at 18 x 14 x 8 inches and markets it for budget-airline size limits.
Four compartments and many small pockets make it easy to separate clean clothes, electronics and toiletries. It is one of the most popular women’s-styled travel backpacks on Amazon, though the cut and straps are unisex enough for most travelers.
Pros & Cons
What we like
- Three packing cubes included
- 18 x 14 x 8 in footprint
- Lots of small pockets
Watch out for
- Soft back, no frame
- Organization can feel busy
Key Specs
- Capacity: 40 liters
- Size: 18 x 14 x 8 in (brand listing)
- Extras: 3 packing cubes
- Compartments: 4 plus pockets
7Tolaccea’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
How We Chose
We compared published specs, materials, fit ranges and features for more than 40 backpacks in the 30 to 50 liter range, then read verified owner feedback to spot durability and comfort problems that spec sheets miss. We did not receive free products, and we do not claim hands-on testing. TOR Scores combine published specs, verified owner feedback and overall value.
Carry-On Rules for 40L Backpacks
Liters measure volume, not dimensions, so a 40L pack can be either carry-on friendly or too long depending on its shape. Check the listed dimensions, not just the capacity.
- Main carry-on. Many US carriers allow roughly 22 x 14 x 9 inches. Most 40L travel packs are built around that size.
- Personal item. Budget airlines often limit free personal items to about 18 x 14 x 8 inches or less. The LOVEVOOK 40L is marketed for that size, but rules vary by airline and fare.
- Weight limits. Some international airlines cap carry-on weight at 7 to 10 kg. Heavy wheeled bags use up a lot of that allowance before you pack anything.
- Liquids. Keep liquids, gels and aerosols in a quart-size bag in an outside pocket so you can pull them out quickly.
Gate agents care about how the bag looks, too. A compressed, tidy pack that fits the sizer is far less likely to be challenged than an overstuffed one.
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.

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.
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.
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.
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 (and its women’s twin, the Fairview 40) is the best 40L backpack for carry-on travel. Choose the tomtoc for laptop-heavy trips and the LOVEVOOK to save money.
