M5040002 Underseat: The Hauptstadtkoffer M5 is a compact travel backpack listed at 40 × 20 × 25 cm for under-seat use. Its listing describes two carrying options, a trolley attachment strap and a stated 20-litre packing volume, though the capacity fields conflict.
At a glance
- The listing describes dimensions of 40 × 20 × 25 cm and positions the bag for under-seat travel, including Ryanair cabin-baggage use.
- It can be carried with padded, adjustable shoulder straps or as a bag with a removable shoulder strap, according to the listing.
- A rear strap is described for attaching the backpack to a trolley's telescopic handle.
- The listing claims 600 g weight and a 20-litre packing volume, but another capacity field says 10 litres.
Pros and cons
Pros

- The trolley attachment strap can help keep the bag on a suitcase handle while travelling.
- Its listed 600 g weight is low for a travel bag, if the manufacturer's figure is accurate.

What to know before buying
Listing details to confirm
The capacity details conflict: the specifications list both 10 Liters and 20 Liters, while the feature text also claims a 20-litre packing volume. The wheel type, combination lock, telescopic handle and tie-down strap are listed, but their relevance to this backpack is unclear. The 40 × 20 × 25 cm size is a manufacturer claim, not confirmation of acceptance by every airline. Check the selected listing and your airline's current baggage rules.
Who is it for?
A good fit for
- Travellers seeking a small bag listed for under-seat cabin use.
- Buyers who want the option of shoulder-strap or removable-strap carrying and a trolley attachment.
Less suited to
- Anyone who needs a confirmed capacity before purchase, given the conflicting 10-litre and 20-litre entries.
- Travellers needing a larger bag or confirmed acceptance across multiple airlines.

Aggregate ratings are mixed, with ratings spread between five-star and one-star categories. That offers limited guidance about practical details such as carrying comfort or capacity, so buyers should weigh the conflicting volume information against their intended use.
