What is a hand luggage duffel and which alternative suits you?
A duffel bag is a soft travel bag with a wide opening and lots of packing space. Perfect for short trips, sports and weekends away. If you want a duffel as hand luggage, focus on the right dimensions, carrying comfort and smart organization. ByMetz offers compact alternatives that provide the same convenience but are optimized for airline requirements and modern travel. Traveling with only an under‑seat item? Choose 40x30x15 or 40x30x20. A very compact option are our Underseaters. Want to see all options together? View our travel bags (duffels).
For hands‑free comfort, choose our expandable hand luggage backpack 40x30x15 to 40x30x20. It combines the volume of a small duffel with the comfort of a backpack, including a laptop compartment and organized pockets. Prefer the look and packing style of a shoulder duffel? Discover our 40x30x20 travel bags with shoulder straps. Want rolling comfort without lifting? See our Travel bags with wheels.
Sizes and airline rules
Each airline has its own rules. As a guideline: 40x30x20 cm or 40x30x15 cm often fits under the seat, while larger cabin sizes are usually charged or restricted. Check the standard cabin size if in doubt, for example Handbagage 55x40x20. For a full overview of common sizes per airline, see our Handbagage sizes – complete guide.
| Size | Use | Benefit |
|---|---|---|
| 40 x 30 x 15 cm | Under the seat | Always with you, quick boarding |
| 40 x 30 x 20 cm | Under the seat | A bit more volume |
| Up to approx. 55 x 40 x 23 cm | Cabin locker | More capacity, often charged |

Is a North Face duffel M allowed as hand luggage?
