When choosing a 40x30x20 travel bag, the material is mainly about finding the right balance between low weight, sturdiness and flexibility. With this compact size in particular, you want a bag that is comfortable to carry, moves with you enough and is suitable for use as a personal item. On this page, you can read what to look for and which type of material often makes the most sense in practice.
Why material matters extra for 40x30x20
A 40x30x20 cm travel bag is usually used as compact hand luggage or an underseater. That means every detail matters. The material determines not only how sturdy the bag feels, but also how easily you can pack it, carry it and slide it under a seat.
For this size, these properties are especially important:
- Low weight - so the bag itself takes up as little as possible of your available luggage allowance and carrying comfort
- Enough flexibility - useful if you want to pack the bag compactly or place it neatly under the seat
- Wear resistance - important when lifting, setting down and travelling frequently by airport, train or car
- Shape and structure - enough firmness to pack in an organised way without making the bag unnecessarily stiff
That is why material choice for a 40x30x20 travel bag is not just about appearance, but above all about practical use.
Which materials do you see in a 40x30x20 travel bag?
Within the ByMetz range, you will specifically come across two types of material for this size: 600D polyester and nylon. Both are suitable for compact travel bags, but they place slightly different emphasis.
600D polyester
600D polyester is a popular material for travel bags because it offers a practical middle ground between sturdiness and ease of use. For a 40x30x20 bag, that is interesting: you want a bag that can handle daily use and travel, but does not feel heavy or stiff.
A 600D polyester model often suits travellers looking for a bag for short trips, city breaks or as a personal bag on the plane. The material usually feels sturdy and is suitable for intensive use without making the bag immediately heavy.
Nylon
Nylon is also a logical choice for a compact travel bag. The material is known for its lightweight character and pleasant suppleness. In a 40x30x20 size, that can be an advantage if you want a bag that moves easily while carrying and packing.
If you prefer a somewhat softer, lightweight bag, nylon is often where you end up. Especially if you often take the bag on short trips or as extra hand luggage, that can be practical.
Should you choose polyester or nylon?
The best choice depends on how you travel and what you find important in use. If you first want to look more broadly at How to choose the right travel bag, that also helps with this decision.
| Property | 600D polyester | Nylon |
|---|---|---|
| Feel of sturdiness | Often a bit more robust | Often a bit more flexible |
| Weight | Lightweight | Lightweight |
| Flexibility | Good balance between shape and suppleness | Often extra supple |
| Suitable for | All-round use and frequent travel | Light, compact and easy-to-carry travel bags |
If you are mainly looking for a bag that feels sturdy and is broadly versatile, 600D polyester is often a safe choice. If you specifically want a lightweight and supple travel bag that moves easily, nylon may be a better fit.
What else should you look at besides the base material?
The main material is important, but it is not the only thing that determines how a 40x30x20 travel bag performs. Also pay attention to the finishing and construction of the bag.
- Zippers and pullers - these take a lot of strain during travel and packing
- Straps and handles - important for carrying comfort and durability
- Shape retention of the bag - useful if you want to pack neatly
- Flexible exterior - pleasant if you want to place the bag under the seat
Some ByMetz models also use metal finishes. That does not say everything about the whole bag, but it can contribute to a sturdier finish on parts that you use often.

Which material choice best suits your use?
If you mainly use the bag for flights, a light and supple material is usually the most comfortable. A compact bag should be easy to carry and easy to place as a personal item. If you mainly want to save weight, take a look at our lightweight hand luggage bags. For Ryanair, this falls within the free small personal bag of 40 x 30 x 20 cm. For example, view hand luggage 40x30x20 if you want to see suitable models straight away.
If you travel more often by train, car or for a short overnight stay, a little more structure is often nice. Your bag then stays organised while packing and feels a bit sturdier during heavier use. For those who want compact storage between trips, foldable hand luggage bags are a practical choice.
If you are hesitating between two materials, do not only look at the material name, but especially at what you need: low weight, suppleness, sturdiness or a combination of these. It is also smart to measure your bag properly so you know for sure that the size is correct.
