Read the verdictResearch-based assessmentOfficial specifications and documented evidence. Not hands-on tested. Research score only. Not a Travistello Pick.
The short answer
The only case in this group that fits inside the cabin envelope many full-service carriers publish, wrapped in the most serious construction here. It is also the most expensive by a wide margin, and nothing Travistello can verify justifies that gap.
Travistello research score
Research-based, using Carry-on Research Model v1.0. No physical test is implied.
At 4.9 kg it is the heaviest case here, but it is also the only one in this group whose published 54.1 by 37.4 by 21.5 cm body fits inside the 55 by 40 by 23 cm envelope many full-service carriers use, as well as easyJet's published large cabin bag allowance of 56 by 45 by 25 cm, which is measured including handles and wheels. It still exceeds Ryanair's published priority allowance of 55 by 40 by 20 cm on depth.
30% of overall scoreA zip-less aerospace-grade aluminium magnesium shell with a published lifetime warranty. The most protective construction Travistello has recorded from this brand, since a zip-less closure removes the usual failure point.
25% of overall score37 litres for 4.9 kg of empty case is the least volume per kilogram in this set, which is what a zip-less full aluminium shell weighs.
20% of overall scoreAn observed EUR 1,099.99 is nearly seven times the cheapest case here and more than twice the Gibraltar, for 1 litre more capacity and 400 g more weight. The construction is genuinely different, but the price is not supported by any measured performance advantage.

Cabin compatibility depends on airline, fare, and route.
Airline-size bounding box
This is a dimensional reference, not a compatibility promise. Airline, route, fare, sizer enforcement, wheels, and handles can change the result.
Evidence & methodology
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.
