Description
An underseat cabin backpack, sized for the plane
This underseat cabin backpack with a minimalist design, made for travel, is perfectly sized to meet airlines’ hand luggage standards. Its stated size is 40 x 20 x 25 cm. On paper, it is within the 40 x 30 x 20 cm small personal bag that Ryanair publishes (October 2026), so check your airline’s rules before you leave. It has a 20 litre capacity and weighs a featherweight 500 g, so it slides easily under the seat without compromising on organisation. Its large main compartment opens flat like a suitcase, ideal for quick access to your belongings. The padded straps and the chest strap ensure optimal comfort on the move. Made of tough polyester, it combines lightness and sturdiness. Whether for a city break, a business trip or a weekend getaway, this bag is a practical and elegant ally.
Compact, organised and cabin compliant
Optimised for air travel, this small lightweight cabin backpack offers well-thought-out inner organisation and superior carrying comfort.
What it holds
A zipped front pocket gives quick access to your essentials, and many inner pockets take accessories and electronics. A strap on the back slides over the handle of a trolley case, and the straps are adjustable and padded.
For weekend trips, take a look at our 20 to 35 L cabin backpack with shoe compartment, in our cabin backpacks collection. You will also find this one among our waterproof backpacks.
