Xkdoai 40x30x20 Ryanair cabin bag 24L
Product description
Key points
If you travel with cabin baggage and want a Ryanair cabin bag that fits the airline’s size expectations, this Xkdoai under seat backpack is built around that 40x30x20cm footprint. The bag is described as a 24L cabin bag, with a fully packed size of approximately 40×30×20cm, and it is said to comply with Ryanair’s standard for this backpack size. Opening up like a suitcase can make packing and access feel more straightforward, especially when you are trying to get organised quickly before boarding. 😊

There are also practical details aimed at everyday trips. A side water bottle pocket helps you keep drinks to hand without having to put them in the main compartment. For valuables, there is a hidden anti theft pocket on the back, which can be useful when you are walking through busy areas. You also get multiple compartments, including space for a 14 inch laptop, so you can keep your essentials separated rather than all mixed together.
The bag is finished with a breathable mesh back panel for comfort while wearing it. The fabric is described as waterproof, which can be handy for wet weather days when you are travelling to and from the airport or dealing with unpredictable UK rain. The overall build and layout is positioned around short trips with lighter packing, rather than long journeys with a lot of luggage, so it’s best matched to quick getaways.



Worth noting: the listed tolerance for manual measurement is 2 to 3cm, so if you are aiming to the millimetre for strict airline checks, it’s sensible to double check how your specific items sit inside the bag when fully packed.

What stands out



The main benefit of this model is the design built around Ryanair cabin bag size expectations, using a 40×30×20cm body size and a travel backpack format. The 180° opening like a suitcase is particularly useful because it helps you pack and retrieve items without having to dig around at awkward angles. In day to day use, that can save time when you need to find documents, chargers, or a change of clothing before you settle in.
It also includes a side water bottle pocket, so you can keep hydration accessible while you travel. That reduces the need to put a bottle into the main compartment, helping to keep the interior cleaner if the drink is condensation heavy. The side pockets are described as large enough for bottles and drinks of different sizes, which is helpful if you carry a larger bottle for a longer queue or a smaller one for shorter legs.

For peace of mind with valuables, there is a hidden anti theft pocket on the back. While no bag can make theft impossible, a concealed pocket is a sensible feature when you are in crowds, moving through terminals, or managing multiple stops. There is also a variety of compartments, including a side pocket for items like slippers or an umbrella, which supports a more organised packing routine.
You will also notice the comfort focused back design, with a breathable mesh material on the back for better wearing feel. The fabric is described as waterproof, which is useful for rainy days when you might be walking between transport links and the airport. 🌧️



It makes sense if you prioritise a compact under seat carry on setup, plus practical compartmenting for electronics, hydration, and daily items, without needing a large suitcase style layout. It might not be the best match if your trips are long and require heavy packing, because the product description positions it for short trips with lighter luggage.
Who it’s for
It’s a good fit if you are planning short trips and want a cabin bag that fits within a 40×30×20cm under seat footprint, with a 24L capacity that supports essentials and a 14 inch laptop. You’ll like it if you prefer a backpack you can open broadly like a suitcase, helping you organise items for quick access during travel. You may also appreciate the anti theft back pocket and the side water bottle pocket for day to day convenience.
It’s not for you if you typically pack for long stays with a lot of bulky items, since the guidance notes it is suitable for short trips with little luggage. It might not suit you if you expect a larger cabin bag for extensive wardrobe packing, because the 24L capacity is set for a compact carry on approach. Before you buy, consider how your travel items will fit within the approximate 40×30×20cm space and whether you are comfortable packing by compartments to keep everything accessible.
