Frequently Asked Questions
Will it fit my airline's cabin allowance?
It measures 40 x 25 x 20 cm when packed, which is sized around the free under-seat bag allowance many airlines offer. Allowances differ by airline and fare type and can change, so please check your airline's current limits before you fly.
How much does it hold?
20 litres — enough for a few days of clothes plus everyday essentials, spread across the main compartment and 6 extra pockets.
Is a power bank included?
No. The bag has a built-in USB charging port — connect your own power bank inside, then plug your phone cable into the port on the outside.
How does the 180° opening work?
The main compartment zips all the way round so the bag opens flat like a suitcase. It makes packing easier and lets you reach items quickly at security.
Can I attach it to my suitcase?
Yes — the trolley sleeve on the back slides over the telescopic handle of your rolling luggage.
Is it waterproof?
The polyester outer is water-resistant, so it handles light rain and splashes. It isn't fully waterproof, so don't submerge it or leave it out in heavy rain.
