How to Choose the Perfect Travel Bag: The Complete Guide to a Smooth Trip
October 23, 2026
The perfect travel bag is chosen by the length of the trip and the airline's rules. For short trips (low-cost), a 20-40 liter backpack that fits the free baggage limits (like 40x20x25 cm) is recommended. For longer trips, choose a durable Cordura duffel bag of 50-80 liters that combines smart compartments, water resistance and ergonomic carry straps.
Types of travel bags: what is the difference and what suits you?
A good trip starts with good packing, and good packing starts with choosing the right bag. Over the years we have seen travelers of every kind: backpackers crossing South America, business people hopping between meetings in Europe, and whole families heading off for a beach vacation in Greece. Each of them has a completely different need when it comes to a travel bag.
The first and most popular type is the duffel bag. It is a wide, flexible sack-style bag, usually made of especially strong fabric, that lets you pack a huge amount of gear without the rigid limits of a hard suitcase. It is perfect for road trips, outdoor trips, reserve duty, or as an extra bag that folds into your big suitcase.
The second type is a dedicated travel backpack. Unlike regular daypacks, these backpacks open like a suitcase (a 180 degree, book-style opening), which gives you easy, quick access to every item without turning the whole bag upside down. They have become a huge hit in recent years thanks to the low-cost revolution, because they let you fly without paying extra for luggage.
The third type is a wheeled travel bag. An excellent hybrid solution that combines the flexibility and light weight of a fabric bag with the convenience of wheels and a telescopic handle, for anyone who wants to avoid carrying weight on their back or shoulders through the endless airport corridors.
Volume and dimensions: how to stay out of trouble with airlines
One of the most common mistakes travelers make is buying a bag that is too big "just in case", and then painfully discovering at the boarding gate that they have to pay a high fee. To make things clear, we gathered the recommended dimensions and volumes for each type of trip:
| Bag type | Recommended volume | Main use | Airline fit |
|---|---|---|---|
| Small low-cost backpack | 20 - 25 liters | Weekends, short flights without paying for luggage | Fits under the seat (Ryanair, Wizz Air) |
| Medium travel backpack | 30 - 45 liters | Trips of 3-5 days, business travel | Cabin baggage (trolley size, overhead bin) |
| Large duffel bag | 50 - 80 liters | Long trips, outdoors, family travel | Checked luggage only |
When you choose a cabin bag, it is important to check the outer dimensions including handles and wheels. Flexible bags have a huge advantage over hard suitcases here: if you are over by a centimeter or two, you can usually "squeeze" the soft bag so it fits into the airline's sizer at the airport.
The materials that make the difference: Cordura, canvas and polyester
A travel bag's durability is measured first and foremost by its fabric and the quality of its stitching. A travel bag has a hard life: it gets thrown into the bus luggage hold, dragged on the floor, exposed to sudden rain and stretched to the limit by last-minute shopping.
Cordura is considered the gold standard of the bag world. It is a nylon fabric with exceptional resistance to abrasion, tears and water. If you are looking for a bag that will last many years of intensive travel, this is the material for you.
Canvas, on the other hand, gives a classic, distinctive vintage look. It is very strong and breathable, but it will usually be heavier and less water-resistant than Cordura, unless it has been specially treated to repel water.
Synthetic fabrics like high-density polyester and nylon (measured in denier, for example 600D or 1680D) offer an excellent combination of light weight, good water resistance and affordable pricing. They suit everyday backpacks and light low-cost bags very well.
The small details that save the trip: compartments, zippers and ergonomics
Beyond material and size, the real comfort of a travel bag shows in the small details and its inner layout:
- Padded back system and shoulder straps: if you chose a backpack, don't compromise on the quality of the straps. They must be wide, padded and made of breathable mesh to prevent sweating and shoulder pain during long walks.
- A dedicated compartment for shoes or dirty laundry: a separate compartment at the bottom or side of the bag lets you keep shoes or dirty clothes away from your clean gear.
- Strong zippers that can be locked: the zipper is the most sensitive point of any bag. Look for thick, quality zippers, ideally with dedicated loops that let you lock them with a small padlock to protect your gear from pickpockets.
- A smart trolley sleeve: a back strap that lets you slide the travel bag onto the telescopic handle of your big suitcase. It is a life-changing upgrade that makes moving through the airport easier and leaves your hands completely free.

Frequently asked questions
What is the difference between a travel bag and a hard-shell suitcase?
A travel bag offers more flexibility, a lighter weight and the ability to squeeze into tight storage spaces or under the seat on the plane. A hard-shell suitcase protects fragile items better and has built-in wheels, but it is heavier and takes up fixed space even when empty.
What size travel bag can I take on board for free with a low-cost airline?
Airlines like Ryanair and Wizz Air allow only a small backpack that goes under the seat in front of you for free. The most common dimensions are 40x20x25 cm or 40x30x20 cm, a volume of about 20 liters.
How do I clean a Cordura or canvas travel bag?
Clean the bag by hand with a damp cloth, lukewarm water and mild soap. Don't put the bag in the washing machine or dryer, as this can damage the water-repellent coating and the ergonomic structure of the back and straps.
Should I buy a travel bag with wheels or without?
If you walk long distances in airports or in cities with paved sidewalks, wheels will make things much easier. On the other hand, if you travel off the beaten track, climb a lot of stairs or want a bag that is as light and flexible as possible, a backpack or duffel without wheels will be more comfortable and practical.
