A cabin bag seems simple to choose, until you get to the gate and discover it won’t fit under the aircraft seat or is heavier than expected. A large main compartment isn’t always practical either if your documents, phone and charger end up buried at the bottom.
The most common pitfalls are:
First, check whether you need a bag for the overhead locker or for the space under the seat. These are usually two different product categories.
An underseat bag, or bag for under the aircraft seat, needs to be compact. The dimensions 40 x 20 x 25 cm are often quoted for a small personal bag, including by Ryanair. The product information for the Kono 40 x 20 x 25 cm states that it is suitable for Ryanair and several other airlines. Always check the current terms for your ticket and airline. A Ryanair cabin bag must meet the requirements of the ticket type you’ve chosen.
For an easyJet cabin bag, permitted sizes and the number of bags allowed can also vary depending on your ticket or any extra cabin baggage you’ve purchased. So don’t rely on the product name alone: compare the height, width and depth with the information on your booking.
A bag measuring 55 x 35 x 25 cm offers noticeably more space and works as a compact cabin bag if your airline accepts these dimensions. According to the product details, the Kono holdall has a capacity of around 48 litres and weighs 0.7 kg. That makes it spacious enough for clothes, shoes and travel essentials, but its overall dimensions may be too large for underseat allowance.
Also consider the weight of the bag itself. If your weight limit is low, choosing a lightweight travel bag leaves more room for your belongings.
Oxford fabric is often used for a water-repellent travel bag because of its sturdy weave and relatively low weight. The product description states that the Kono bags are water-repellent. In practical terms, this means protection from light rain, splashes and spilled drinks. It’s no substitute for a waterproof cover or dry bag.
Check the fastening, too. A sturdy zip helps keep your belongings inside, while internal pockets stop small items from moving around loose in the main compartment.
These features are useful for a weekend away or a business trip:
A travel bag with a trolley sleeve is especially useful when you’re carrying several pieces of luggage. Check that the sleeve is wide enough for your suitcase and that the bag stays stable as you walk.
Why it suits this profile: A compact choice for short flights, an overnight stay or everyday use as a gym bag. With a capacity of around 20 litres, it’s easy to organise without unnecessary bulk.
The stated dimensions of 40 x 20 x 25 cm make it easier to compare the bag with underseat rules. Always check your own ticket conditions, too.
Weighs 0.5 kg, holds around 20 litres, with an adjustable shoulder strap and rear trolley sleeve.
Why it suits this profile: A good fit for travellers who want to pack more clothes and kit for a weekend away or business trip, as long as the size meets cabin baggage rules.
All three external dimensions are clearly stated, so you can check in advance whether 55 x 35 x 25 cm is within your flight’s limit.
Around 48 litres of capacity, weighs 0.7 kg, with a front pocket, mesh pocket and three carrying options.
Why it suits this profile: A useful option for moving house, storage or bulky luggage. At 73 x 34 x 37 cm, this set isn’t designed to be a standard underseat bag.
The large dimensions make it clear these bags shouldn’t be bought as small cabin luggage. Use them for storage, moving house or luggage outside the underseat category.
Set of four, with shoulder straps and handles; the product title also mentions wheels and hard-wearing material.
Why it suits this profile: A practical option for work, school and train journeys when a laptop compartment matters more than the shape of a weekend bag.
The product title mentions a water-repellent finish, multiple compartments and a luggage strap. Check the exact dimensions before using the backpack as cabin baggage.

No. Only compact models within the airline’s personal item size limits are designed for this. A 55 x 35 x 25 cm bag is generally larger than an underseat model. Check your ticket conditions before you travel.
Yes, especially if you regularly walk through stations or airports. An adjustable strap distributes the weight differently from handles. If you’re carrying heavier items, a trolley sleeve can make things easier by letting you attach the bag to a suitcase.
That depends on its weight, how often you use it, the zips and seams, and how you store it. Avoid overfilling the compartments, clean the bag according to the product instructions and store it somewhere dry. If the fabric is water-repellent, it’s best not to leave the bag wet for long periods.
