Finding the best carry-on backpack for international travel means matching the bag to your specific travel habits and packing style. The tomtoc Travel Backpack 40L and the Osprey Daylite Expandable 26+6 represent the two extremes of this category.
1. tomtoc Travel Backpack 40L
Best for: Travelers who want a suitcase-style opening for easy organization.
The tomtoc Travel Backpack 40L prioritizes structure. Its main compartment opens like a suitcase, which makes packing clothes and using organizers much simpler than a top-loading bag. The dedicated laptop and iPad sleeves provide extra protection for your tech, keeping your devices separate from your clothes.
This bag is a strong choice if you prioritize security at the airport, as the TSA-friendly compartment allows for quick scanning. However, it isn’t the right fit for someone who needs a highly compressible bag for light, everyday use, as its rigid, rectangular shape stays bulky even when not completely full.
Good if:
- You carry both a laptop and a tablet.
- You prefer packing cubes for organization.
- You need a bag that fits standard carry-on requirements.
Skip it if:
- You require a bag that fits under an airplane seat.
- You want a minimalist, non-tech-focused aesthetic.
2. Osprey Daylite Expandable 26+6
Best for: Someone who needs a versatile personal item for short trips.
The Osprey Daylite Expandable 26+6 helps avoid overhead bins. Its standout feature is the ability to expand, giving you extra room for souvenirs or extra gear without needing a larger, heavier bag. The AirScape backpanel keeps your back ventilated, which is helpful if you’re walking through terminals for hours.
This bag is ideal for a minimalist traveler who values mobility and a lightweight frame. It isn’t designed for someone going on a long trip who needs to pack multiple pairs of shoes or heavy winter clothing, as its smaller capacity and slim profile will quickly reach their limit.
Good if:
- You want to keep your bag under the seat in front of you.
- You prioritize a lightweight carry experience.
- You move frequently and need a nimble, compact pack.
Skip it if:
- You’re packing for a trip longer than a weekend.
- You carry large, bulky electronics or professional equipment.
3. LOVEVOOK 40L Travel Backpack
Best for: Professionals who need to carry a very large laptop.
The LOVEVOOK 40L Travel Backpack offers high-capacity organization. With a dedicated compartment for a 17.3-inch laptop, it accommodates larger machines that many other packs can’t fit. The inclusion of packing cubes and a specific shoe bag makes it a ready-to-go solution for business trips.
This bag works well for someone who wants to keep their toiletries and shoes separate from their clothing. It isn’t ideal for someone who prioritizes a rugged, outdoor-focused design, as its features are tailored toward business and urban travel environments.
Good if:
- You travel with a large-screen laptop.
- You want pre-included packing cubes and shoe storage.
- You value having many small pockets for accessories.
Skip it if:
- You want a bag designed specifically for hiking or outdoor terrain.
- You dislike having too many small, individual pockets.
4. Tolaccea Travel Backpack 40-50L
Best for: A traveler who needs to switch between a backpack and a briefcase.
The Tolaccea Travel Backpack offers multiple carrying modes. You can wear it as a backpack, carry it as a briefcase, or use the shoulder strap to carry it as a duffel. The suspended laptop compartment is a smart touch for protecting your computer when you set the bag down quickly.
This bag is for the traveler who needs to look professional in a meeting but still needs the comfort of a backpack for transit. It isn’t the right choice for someone who strictly wants a lightweight bag, as the added structure for the different carrying modes makes it a heavier, more substantial pack.
Good if:
- You need to convert your bag into a briefcase style.
- You want quick, side-access to your laptop.
- You appreciate extra gear storage like tactical straps.
Skip it if:
- You need a bag that fits under an airline seat.
- You prefer a very simple, lightweight bag with no extra straps.
5. Lumesner 40L Expandable Travel Backpack
Best for: The traveler who wants a complete kit with included accessories.
The Lumesner 40L Expandable includes four packing cubes. The built-in USB port is a convenient addition for charging your phone while on the move. Its capacity is flexible, making it a good all-rounder for trips lasting between three and seven days.
This is a great kit for a traveler who doesn’t want to buy extra organizers separately. It isn’t for someone who prefers a very slim, streamlined bag, as the expandable nature and extra accessories can make the bag feel quite wide when fully packed.
Good if:
- You want a full set of packing cubes included.
- You like having a USB charging port on your bag.
- You need to adjust your bag size based on the trip length.
Skip it if:
- You already own your own preferred set of packing cubes.
- You prefer a bag with a more rigid, slim shape.
6. MATEIN Carry On Backpack
Best for: Those who need the largest possible carry-on capacity.
The MATEIN Carry On Backpack offers up to 45 liters expanded. The compression straps are a key feature here, as they help keep the bag’s profile steady and stop your gear from shifting around inside while you move through the airport.
This bag is an excellent choice for someone who struggles to pack light. However, it isn’t the right bag for a traveler who wants a discreet, small-looking pack, as the large, expandable design is quite noticeable and can be heavy when filled to its maximum capacity.
Good if:
- You need the maximum possible volume for a carry-on.
- You want to compress your load to keep it stable.
- You need to hide the shoulder straps for a clean look.
Skip it if:
- You struggle with the weight of a heavy, fully loaded bag.
- You want a small, minimalist carry-on for short trips.
7. BAGSMART Travel Backpack
Best for: Travelers who need to keep wet items separate from dry clothes.
The BAGSMART Travel Backpack features a PVC-lined wet pocket. The side shoe compartment is also very useful for keeping the rest of your gear clean. It’s designed to be lightweight, which helps when you have to carry a lot of items for a longer trip.
This bag is a solid choice for those who visit gyms or go to the beach during their travels. It isn’t the best choice for someone who needs to pack a massive amount of gear, as its dimensions are slightly smaller than the 40L-plus competitors on this list.
Good if:
- You need a separate place to store your shoes.
- You want a soft, comfortable material.
Skip it if:
- You need a massive amount of space for a week-long trip.
- You prefer a more rigid, structured aesthetic.
8. Vancropak Carry On Backpack
Best for: Someone who wants a high level of security and organization.
The Vancropak Carry On includes lockable zippers. The combination of wet/dry separation, a dedicated shoe compartment, and included packing cubes makes this one of the most organized bags in the group. It’s designed specifically to make airport security as fast as possible.
This bag is ideal for the traveler who is worried about keeping their things organized and secure. It isn’t for someone who prefers a simple, single-compartment bag, as the many pockets and dividers can sometimes make it harder to find a single, large item.
Good if:
- You want built-in security features like lockable zippers.
- You need a dedicated shoe compartment.
- You want to keep wet and dry items separated.
Skip it if:
- You prefer a simple, open-main-compartment layout.
- You want the lightest possible backpack construction.
9. Osprey Sojourn Porter 46L Travel Backpack
Best for: Someone looking for a durable, high-quality bag for long-term travel.
The Osprey Sojourn Porter 46L is built for travel. Its StraightJacket compression system is excellent at keeping your gear secure and reducing the bag’s bulk when it isn’t full. The ability to tuck away the harness and hipbelt is a major plus for protecting your bag during transit.
This bag is a top pick for a traveler who wants something that will last for years. It isn’t for the person who wants a simple bag, as the focus here is on heavy-duty materials and a more premium, structured harness system that’s heavier than simpler packs.
Good if:
- You want a highly durable, long-lasting bag.
- You need to compress your load effectively.
- You want a secure harness that can be hidden away.
Skip it if:
- You’re looking for the lightest possible bag.
- You don’t need a hipbelt for weight distribution.
10. Osprey Daylite 44L Carry-On Travel Pack
Best for: A versatile traveler who wants a balance of space and comfort.
The Osprey Daylite 44L is a middle-ground bag. It offers a large capacity that’s still manageable, and the clamshell opening makes it very easy to pack. The AirScape backpanel ensures that you stay comfortable even when the bag is fully loaded for a long trek through an airport.
This bag works well for someone who wants a reliable brand and a straightforward, functional design. It isn’t the right choice for someone who needs specialized features like a wet pocket or a dedicated shoe compartment, as this bag sticks to the essentials of travel.
Good if:
- You want a reliable, well-ventilated carry-on.
- You prefer a clamshell opening for easy packing.
- You appreciate a clean, simple design for multiple uses.
Skip it if:
- You need extra organizational features like wet pockets.
- You’re looking for the absolute largest capacity available.
Choosing the Best International Travel Carry-On Backpack
Many of the 40L-plus bags, such as the tomtoc Travel Backpack 40L, LOVEVOOK 40L, and Lumesner 40L, share a similar structure. They all focus on the clamshell opening and dedicated laptop storage. If you’re choosing between these, look at the extra features—like included packing cubes or specific shoe pockets—rather than the main volume. Bags like the Osprey Sojourn Porter 46L and Osprey Daylite 44L offer a more premium harness system, which provides better comfort for those who carry their bag for long periods. The choice often comes down to whether you want a bag that feels like a piece of luggage or a bag that feels like a traditional, comfortable backpack.
Still Not Sure?
How often will I really use it?
If you travel once or twice a year, a feature-heavy bag like the LOVEVOOK 40L might be overkill. However, if you’re a frequent traveler, the durability and comfort of the Osprey Sojourn Porter 46L are designed to support heavy loads during long trips.
What do I already own that this has to work with?
Think about your current electronics. If you carry a massive 17-inch laptop, the LOVEVOOK 40L or Vancropak Carry On are your best bets. If you already have your own favorite packing cubes, you might prefer the MATEIN Carry On Backpack, which gives you the space without forcing you to pay for extra accessories you don’t need.
What am I most likely to regret choosing?
Most travelers regret choosing a bag that’s too heavy or too bulky to fit their needs. The Osprey Daylite Expandable 26+6 is the safest choice for airline size limits. It is small and versatile.
Frequently Asked Questions
What does the bag require from me week to week?
Most of these backpacks require very little maintenance. You should check the zippers for debris after a trip and wipe the exterior with a damp cloth if it gets dirty.
What happens when the bag is outgrown or used up?
If you find you need more space, look for a bag with an expandable design like the MATEIN Carry On Backpack. High-quality recycled fabrics, like those in the tomtoc bag, are designed for long-term use.
Would a more capable bag have suited me better?
A more capable bag usually means more weight and bulk. If you struggle to carry your bag through the airport, it may be too large for your comfort.
Are there specific packing techniques for these bags?
Packing cubes are the most effective way to maximize the volume of a 40L-plus backpack. By compressing clothes into cubes, you fit more items into the main compartment while keeping the bag balanced. This also makes it easier to access specific items without unpacking the entire bag during security checks.
Closing
The best choice is a balance between your packing habits and your comfort. If you want a structured, suitcase-like experience for a long trip, the tomtoc Travel Backpack 40L is a reliable, organized choice. If you prefer a nimble, compact bag for shorter journeys, the Osprey Daylite Expandable 26+6 keeps your travel stress-free. Take a moment to check your airline’s size policy and choose the one that fits your typical trip duration.
