The Idea

"A bag too small for a weekend trip, a dead phone before the gate, and a rucksack that won’t sit on a suitcase handle are three versions of the same problem — a 36–55 L expandable, waterproof backpack with USB charging and a luggage strap is the travel carry that solves all three."

Why You’ll Like It36–55 L · Expandable · USB Charging · Waterproof · Luggage Strap

01Waterproof Construction — Protected on Every Journey

The waterproof outer keeps a laptop, documents, and travel essentials dry through rain, transit, and unexpected weather — the bag that removes the need for a separate rain cover or a last-minute rethink every time conditions change between the hotel and the terminal.

02USB Charging Port — Power Through the Journey

The external USB port connects to a power bank stored inside the bag, keeping a phone or earbuds charged without opening the bag or hunting for a socket — the feature that keeps devices topped up from departure to arrival on a long travel day or a full day on the move.

03Expandable Design — 36 to 55 L on Demand

The expandable construction takes the bag from a streamlined 36 L for a day trip to a full 55 L for a longer journey — the flexibility that removes the need to own two separate bags for two different trip lengths, without the bulk of carrying a half-empty large bag every day.

04Luggage Strap — Sits on the Suitcase Handle

The rear luggage strap slides over a suitcase trolley handle, keeping the backpack secure and hands free through airports, stations, and hotel lobbies — the detail that makes the bag a proper travel companion rather than a bag that has to be carried separately alongside a suitcase.
