The short answer

Best for travellers who want the option of more space on the way home.

The most capacity in this group and the only expansion, and it pays for both with a depth that already exceeds the larger European cabin allowance before you use the zip. Read it as a small checked bag that happens to be carry-on sized, not as a cabin case.

Why it stands out

  • 45 litres expanding to a published 50, the only expandable case in this group
  • A top-opening design with a documented TSA-approved lock and dual spinner wheels
  • German-made Makrolon polycarbonate over a 100% RPET recycled polyester lining, with a lifetime warranty

Know before buying

  • At 25.9 cm deep it exceeds easyJet's published large cabin bag allowance of 56 by 45 by 25 cm, which is measured including handles and wheels, so it is not a cabin bag on that airline before it is expanded at all
  • It exceeds Ryanair's published priority allowance of 55 by 40 by 20 cm on depth by almost 6 cm
  • LEVEL8 publishes the 5 litre expansion but not the external depth when expanded, so the expanded footprint is unknown
  • At 4.1 kg it is mid-weight, and the expansion adds volume without adding allowance, so a full case can reach an airline weight limit before it looks full

Travistello research score

7.9/ 10

Why it earned this score.

Research-based, using Carry-on Research Model v1.0. No physical test is implied.

01

Portability

6.6

4.1 kg is mid-weight, but the 25.9 cm depth exceeds easyJet's published large cabin bag allowance of 56 by 45 by 25 cm, measured including handles and wheels, and exceeds Ryanair's published priority allowance of 55 by 40 by 20 cm by almost 6 cm. It is the only case in this group that clears neither airline unexpanded.

Build and warranty

8.5

German-made Makrolon polycarbonate over a 100% RPET recycled polyester lining, with the published lifetime warranty. Impact behaviour remains a manufacturer claim.

25% of overall score
03

Capacity

9.2

45 litres rising to a published 50 through a central expansion zip. That is the most in this group, and the only case here that can change its own volume.

04

Value

7.6

An observed EUR 349.99 buys the expansion and the largest capacity here, on a case whose external depth rules it out of the cabin on the two airlines this set is measured against.

05

Organization

8.2

A top-opening layout, a documented TSA-approved lock, and dual spinner wheels with precision ball bearings. The top opening is a genuinely different packing proposition from a clamshell.

Evidence & methodology

What we know, and what we do not.

A 0 to 10 weighted research model using normalized manufacturer specifications and documented evidence. Portability (30%), capacity (20%), build and warranty (25%), organization (10%), and value (15%) are scored independently. Manufacturer claims remain labelled as claims, price judgments are time-stamped, and no hands-on durability or wheel-performance claim is made without physical testing.
