1. tomtoc 40L Travel Backpack
Best for: Travelers who want clean organization and quick tech access.
The tomtoc 40L Travel Backpack opens flat like a suitcase for easy packing. Its separate tech area holds up to a 17-inch laptop and a 13-inch iPad, opening 90 to 180 degrees for airport checkpoints. Built with recycled polyester fabric from PET plastic bottles and YKK zippers, it keeps daily clutter in check.
With dimensions of 20.47 x 12.99 x 9 inches, the usable capacity ranges between 38L and 40L. The 3D padded back panel and chest strap help distribute weight, but it lacks a hip belt.

This bag features three carrying modes: standard backpack straps, a side briefcase handle, and a crossbody strap stored inside the bottle pocket. If you want a small bag that sits at your feet, this frame is too large.

The MATEIN Carry On Backpack weighs 2.2 pounds and measures 19 x 13 x 8 inches when unexpanded. Unzipping the expansion zipper expands storage up to 45L to accommodate clothing and camera gear. External compression straps help pull the load tight, which saves vertical space and reduces stress on the lockable zippers.
Shoulder straps tuck away to convert the bag into a briefcase. The front pocket holds small items like phones, but the internal laptop storage space is integrated into the main body rather than separated into an independent drop-proof compartment.
Good if:
- You want a lightweight empty bag starting at 2.2 pounds.

This pack integrates interior mesh organizer pockets, a padded laptop sleeve, and a TSID luggage registration tag for lost bags. The substantial foam sidewalls protect internal electronics, but they add rigid bulk that can’t squash down flat. Travelers wanting an ultra-flexible shell might find the structured walls cumbersome in tight spaces.
Good if:
- You want a stowaway hipbelt to stabilize heavy gear.
- You value rigid, padded sidewalls to protect contents.
- You want a built-in lost luggage identification system.
Skip it if:
- You prefer a soft, frameless bag that packs down flat.

It features an adjustable sternum strap to stop the bag from bouncing during long walks across European train stations. The package includes two packing cubes and a shoe pouch, along with an internal waterproof wet pocket. However, it doesn’t include a hip belt, so total weight rests squarely on your chest and shoulders.

Still Not Sure?
How strict are your European flight plans?
If you plan to fly on budget regional airlines within Europe, baggage dimensions matter more than extra volume. Sized at 18 x 14 x 8 inches, the LOVEVOOK 40L Carry On fits into tight personal item boxes under airplane seats, preventing gate-check fees.
How much walking will you do with full luggage?
Rolling luggage fails on cobblestones, making backpack suspension critical for walking across old towns. If you must carry your bag across town, the Osprey Sojourn Porter 46L offers a stowaway harness and hipbelt that routes weight to your hips rather than straining your neck.
Do you prefer modular packing or built-in dividers?
Some travelers want clear pockets and separate compartments, while others use organizers. If you want a complete set out of the box, the Lumesner 40L Expandable Backpack gives you four matching packing cubes, including a transparent toiletry bag and a shoe pouch.

Frequently Asked Questions
What size backpack fits European budget airlines without checking?
A bag measuring 18 x 14 x 8 inches fits most budget personal item gauges. The European Commission air passenger rights framework notes that carry-on limits vary by carrier, so always verify your airline’s specific sizer dimensions before packing.
Can a travel backpack hold an extra pair of shoes separately?
Yes, several travel backpacks offer dedicated compartments that separate dirty footwear from your clean clothes. The Ponhog 50L Convertible Duffle and the coofay Waterproof Travel Backpack both feature isolated shoe pockets built into the bottom of their frames.
What is the advantage of a 180-degree suitcase opening?
A 180-degree suitcase opening allows the backpack to unfold completely flat like a book. This design lets you arrange your clothes neatly, inspect contents easily, and pass through airport security checkpoints without pulling all your folded items out of the bag.
Is an expandable travel backpack better than a fixed frame?
An expandable backpack offers daily flexibility, letting you pack compact for the flight out and expand the zipper for souvenirs later. The Tolaccea 40-50L Travel Backpack lets you expand internal capacity by ten liters whenever your packing volume increases during your travels.
Conclusion
If you want a dedicated harness system for heavy loads, choose the Osprey Sojourn Porter 46L, but if you prefer included organizers and personal item sizing, pick the LOVEVOOK 40L Carry On. Check your airline’s baggage rules today to pick the right frame for your journey.
