The short answer

Best for travellers who want the lightest case and the smallest footprint.

The value entry point, and the case that comes closest to a strict cabin allowance without reaching it. It is the lightest and shortest option here, but its depth still rules out a Ryanair priority boarding bag.

Why it stands out

  • 3.5 kg, the lightest in this group
  • 39 litres from the smallest published body here
  • Lifetime warranty at the lowest observed price in the set

Know before buying

  • The 23.5 cm depth exceeds Ryanair's published priority allowance of 55 by 40 by 20 cm, so it cannot travel as a Ryanair priority bag
  • LEVEL8 publishes these dimensions without the including handle and wheels qualifier it uses on its 20 inch cases, so the real external footprint may be larger
  • Interior organization is less documented than on the dearer models
  • Shell durability, wheel wear, and handle rigidity are not independently tested

Travistello research score

8.5/ 10

Why it earned this score.

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

01

Portability

8.6

At 3.5 kg it is the lightest case Travistello has recorded from this brand, and its 51.5 cm length is the shortest here. Its 23.5 cm depth still exceeds Ryanair's published priority allowance of 55 by 40 by 20 cm, so it is not a Ryanair priority bag.

Build and warranty

8.4

German-made Makrolon polycarbonate with a lifetime warranty published on the product page. Impact behaviour is a manufacturer claim, not a tested result.

Capacity

8.2

39 litres inside a case published at 35 by 23.5 by 51.5 cm is a strong ratio for the smallest body in this group.

Value

9.4

At an observed EUR 159.99 it is the cheapest case in this set and still carries the lifetime warranty, which makes it the strongest value proposition here.

Organization

7.4

A TSA-approved combination lock and 360 degree spinner wheels are documented. LEVEL8 publishes less interior detail for this model than for its dearer cases.

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.
