Finding the best travel backpack for carry on is about matching your packing habits to the right architecture. Whether you need a bag that slides under an airline seat or one that maximizes overhead bin space, the primary differences lie in capacity, organization, and how the bag handles weight. If you travel with a large laptop, the tomtoc 40L Travel Backpack is a top contender for its tech-focused design, while the Osprey Daylite Expandable is better for those who prioritize a lightweight, compact personal item.
1. tomtoc 40L Travel Backpack
Best for: Travelers who need a secure, organized home for a large laptop.
This bag is built for those who carry significant tech gear and want to breeze through airport security. The TSA-friendly compartment opens 180 degrees.
The capacity is flexible, ranging between 38-40L depending on how you pack. The suitcase-style opening makes it easy to organize clothes, while the dedicated pockets for glasses and liquids keep smaller items from getting lost at the bottom of the bag.
Good if:
- You carry a laptop up to 17 inches.
- You prefer a clamshell, suitcase-style opening.
- You want sustainable, recycled fabric materials.
Skip it if:
- You only need a small bag for short, overnight trips.
- You prefer a bag with a more minimalist, less tactical look.
2. Osprey Daylite Expandable
Best for: Someone seeking a versatile personal item that fits under most airline seats.
This pack is built for agility. It’s lightweight and features an AirScape backpanel, which helps keep you cool when moving quickly through a terminal. The standout feature is the ability to expand the main compartment by 2 inches, adding 6 liters of space when you need it for souvenirs or extra gear.
It’s designed to meet personal item size requirements for most major airlines. While it’s smaller than dedicated 40L travel packs, its smart layout—including side water bottle pockets and a dedicated tech sleeve—makes it highly functional for shorter trips or as a secondary bag.
Good if:
- You want a bag that fits under the seat.
- You value a lightweight design for long days of walking.
- You need a bag that can expand for extra packing room.
Skip it if:

3. LOVEVOOK 40L Travel Backpack Flight Approved Carry on Backpack
Best for: Frequent flyers who want an all-in-one organization system.
This backpack is designed to take the stress out of packing. It comes with three extra packing cubes—two for storage and one specifically for shoes—which helps keep your belongings separated. The inclusion of a wet pocket is a thoughtful touch for storing toiletries or damp clothes away from your electronics.
It features a 180-degree opening for quick security checks. The shoulder straps are thickened for comfort and the bag uses durable, no-slip metal zippers.
Good if:

Skip it if:

Where These Overlap
Many of the bags on this list share the same core DNA: a 180-degree clamshell opening, a dedicated laptop sleeve, and a luggage pass-through strap. Products like the tomtoc 40L, LOVEVOOK 40L, and Taygeer TSA Carry On are all aiming for the same “TSA-friendly” traveler who wants to avoid checked bag fees. The choice between these often comes down to the included extras—like the packing cubes in the LOVEVOOK or the specialized shoe bag in the Taygeer—rather than a difference in basic quality. If you’re struggling to choose between these, look at your current accessories: if you already own packing cubes, you might prefer the tomtoc for its build quality, but if you want an all-in-one kit, the LOVEVOOK is the better value.
Still Not Sure?
How often will I really use this?
If you’re a casual traveler taking one trip a year, you likely don’t need the heavy-duty features of the Tolaccea 50L. A simpler, lightweight bag like the Osprey Daylite Expandable will serve you better without feeling bulky.
What do I already own that this must work with?
Check your laptop size first. If you carry a computer with a large, expansive screen, many standard bags won’t work, making the Fxcelets Travel Backpack or the tomtoc 40L your necessary choices.
What am I most likely to regret choosing?
The most common regret is buying a bag that’s too big to fit under the seat when you wanted a personal item. Always check the TSA carry-on guidelines to ensure your bag meets security standards for the specific items you plan to pack.
Frequently Asked Questions
What does this bag ask of its owner week to week?
Most of these travel backpacks are low-maintenance, but they do require you to keep zippers clear of fabric to ensure smooth operation. If your bag has a wet pocket, make sure to dry it out completely after you return from a trip to prevent any odors or mildew buildup inside the compartments.
What has to be replaced or renewed to keep it working?
These bags don’t have parts that require regular replacement. The only maintenance is checking the zipper teeth for debris after a long trip. If you use a password lock on a bag like the SHRRADOO, keep your code written down in a secure place, as resetting a locked bag is difficult.
What happens when the bag is outgrown or used up?
If you find you’re consistently packing more than your bag can hold, it’s time to look for an expandable model like the MATEIN or Tolaccea. When a bag reaches the end of its life, check if the fabric can be recycled; many brands like tomtoc use recycled PET, which is often accepted at textile recycling centers.
Would the more capable bag on this list have suited me better?
A more capable, larger bag usually means more weight. If you find yourself struggling to carry your bag through the airport, you might have chosen too much capacity. A larger bag is only “more capable” if you actually have the gear to fill it; otherwise, a smaller, lighter bag is almost always more comfortable to carry.
Closing
The best travel backpack for you depends on whether you prioritize maximizing your capacity or maintaining a compact profile for under-seat storage. For those needing maximum space and organization, the tomtoc 40L Travel Backpack is a reliable choice. If you prefer a smaller, more agile bag, the Osprey Daylite Expandable is the way to go. Check your specific airline’s size limits before you buy.
