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

01

Portability

9.4

At 2.2 kg for a 55 × 40 × 20 cm cabin case, Proxis leaves unusually generous baggage allowance for packing. Wheel feel has not been tested by Travistello.

02

Build and warranty

9.0

The ROXKIN polypropylene shell and 10-year limited global warranty are strong documented signals, not an independent durability test.

03

Capacity

8.9

Official volume is 40 L, expanding to 46 L as depth grows from 20 to 23 cm. Expansion is useful away from strict cabin limits.

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.
