    • 1 pair of trousers
    • 1 toiletry pouch
    • 1 pair of low-profile shoes

A loaded figure is only published when we can also publish what was inside it. Where you do not see a loaded row, it is because that record does not exist yet — not because the bag stays the same size when it is full.

02Check it against your own limit

Put your three numbers in

We subtract them from the figures above and show the gap on every edge. No verdict, no promise — the arithmetic and nothing else.

Size Ledger

Enter the limit you have been given

Take the three numbers your carrier publishes for your ticket and type them in. We hold no carrier data of our own, so nothing here can go out of date.

Published limit

We compare numbers, not policies. Airlines change limits and measure differently at the gate.

Arithmetic result

Waiting for three numbers

Nothing is compared until you type a limit. We do not guess, and we do not store a list of anyone else’s rules.

03Specification

What it is made of

Materials
  • 600D recycled polyester
  • Recycled ripstop polyester
  • Polyurethane inner coating
Hardware
Nylon coil zippers with moulded pulls, anodised aluminium D-rings
Water-resistant shell

Sprayed with 2 L of water at 20 °C from 30 cm for 3 minutes, closed and held at 45°. Zippers, seams and the base panel are not sealed and are not part of the test.

This is a resistance rating under the stated test, not a waterproof rating.

Suggested load

Rated to 9 kg. Damage caused by carrying more than the rated load is wear, not a fault — see the product safety page.
