With the great development in the design of travel bags, modern bags have adopted the full opening system (Clamshell Opening) —, which is a system that opens the bag as if it were a traditional travel bag (Suitcase) to facilitate packing clothes and organizing tools without the need to empty the entire bag.

  Before moving on to the comparison, make sure that the bag you choose includes the following criteria: Approved dimensions for flight (Carry-On Approved): Dimensions not exceeding $55\times 40\times 20\text{cm}$ to ensure that it is brought with you to the aircraft cabin without fees.   Comfortable Orak Belt System (Hip Belt): Weight moves the bag from the shoulders to the tub for back comfort while hiking.   Protected Laptop Pocket: Designed for digital travelers (Digital Nomads) and those working on the go.

   4. How do you choose the perfect bag to carry inside the plane? (Quick Buy Guide)

To ensure that you do not encounter any problems at the airport boarding gates, observe the following criteria: 

  1* Standard Dimensions and Sizes: Make sure that the bag dimensions do not exceed (55 × 35 × 25 cm), which are acceptable sizes for most budget and traditional airlines.

2* Opening Method: Always choose bags with full front opening (Clamshell) to facilitate security inspections and organize clothing.  

3* Empty bag weight: Remember that some heavy bags when empty (such as bags made of very rough fabric) may consume a large portion of the permissible weight in the aircraft cabin (often the permissible weight is between 7 to 10 kg). 

 4* Foldable Belts: The hide shoulder and waist straps feature protects the straps from damage while shipping the bag crosswise or placing it in tight spaces. 

Here are answers to the most frequently asked questions about choosing and traveling in a travel backpack:

1. Carry-on baggage rules and sizing

Can a 40 liter backpack be used as an airline handbag?

Most major airlines: Yes. The standard limit for top box dimensions is 22 x 14 x 9 inches (55 x 35 x 23 cm). Bags like the Osprey Farpoint 40, Peak Design 45L (compressed), and Patagonia Black Hole MLC 45L are clearly designed to fit standard overhead bins.

Budget airlines (Ryanair, Wizz Air, EasyJet, AirAsia): Standard carry-on bag dimensions may be appropriate, but weight limits (often 7 kg/15 lbs) or strict personal item dimensions (under-seat fit) can be an issue. If you're flying on budget airlines, a bag weighing 30 to 35 liters and packed under 7 kg is safer.

Can a travel backpack be placed under the seat as a "personal item"?

Less than 30 litres: usually yes (e.g., Patagonia MLC 30L, Cotopaxi Allpa 28L, or Tomtoc 28L/30L), provided they are not overstuffed. Here are answers to the most frequently asked questions about choosing and traveling in a travel backpack:

2. Bag design and features

Shell Loading (Panel Loading) vs. Top Loading: Which is Better?

Shell (bag-shaped): Opens fully around three sides. Best for travel because you can access any item without having to search the entire bag.

Top Loading: Belts on top like a traditional hiking backpack. Best for hiking in the wilderness, but inconvenient to travel due to difficult access to equipment below.

How important is a hip belt in a suitcase?

40 liters+ or heavy loads (10+ kg/22+ lbs): necessary. A proper padded hip belt transfers up to 70–80% of the weight from your shoulders to your hips.

Less than 35 liters or light urban transport: optional. Basic belt straps help prevent the bag from swinging, but padded hip straps are less important for shorter distances.

3. Packing and equipment care

Do I still need packing cubes if my bag has built-in compartments?

Yes, for most bags. Packing cubes compress clothes, keep items organized by category, and make the hotel unpacking process quick.

Exception: Bags like the Cotopaxi Allpa 35L have built-in zippered mesh dividers that act as integrated packing cubes.

How do I clean my suitcase after a long trip?

Empty all pockets and dispose of debris.

Clean external stains using warm water, mild dish soap, and a soft cloth or brush.

Do not wash or dry travel backpacks in a washing machine with internal frames, coated waterproof liners, or structured foam back panels, as moving the machine will damage the TPU coatings and waterproof gaskets.
