If you want to keep flight costs down in 2026, a well sized underseat cabin bag from Cabin Max is one of the cheapest ways to do it. This guide focuses on their most budget friendly backpacks and holdalls that still work well for real world travel and outdoor adventures.
We have picked out the lower priced Cabin Max bags that hit the common 40 x 20 x 25 cm underseat allowance. The focus is on saving money while still getting something practical enough for weekends away, city breaks and light outdoor use.
Every bag here has trade offs. Some are as cheap as it gets in the Cabin Max line up, while others cost a touch more but feel better to live with day to day. The aim is to help you decide where to save, and where a few extra pounds within the same brand is money well spent.
These recommendations are based on a close look at Cabin Max’s range, focusing on capacity, airline friendly dimensions and what you actually get for your money. We are not just chasing the lowest price tag, but highlighting models that still look like sensible buys for frequent travellers and occasional adventurers alike.
We pay attention to real world considerations such as how easy a bag is to pack to airline limits, how versatile it will be for weekends away and day trips, and whether the design feels robust enough for repeated journeys. Where review data is available, it helps guide which cheaper models have kept owners happy and which are best avoided.
The goal is simple: to point you towards the more affordable Cabin Max options that feel like genuine value, rather than bargain basement bags that you will quickly want to replace.
We started by looking at the lower priced end of the Cabin Max range that fits into the underseat, 20 litre bracket. These are the models most people turn to when they want to travel light and avoid extra cabin bag fees, so price and dimensions matter just as much as style.
From there, we prioritised bags that make smart use of the 40 x 20 x 25 cm footprint, offer straightforward packing and are likely to handle repeated flights and transfers. Where ratings exist, we prefer models that have kept owners broadly satisfied rather than ultra cheap bags with worrying feedback.
We also aimed for a mix of formats so you can pick what suits your trips: simple backpacks that double as daypacks, classic holdalls that tuck neatly under a seat, and a roll top option that offers a bit more flexibility for everyday use. All of them sit on the cheaper side of Cabin Max’s line up, but each offers a slightly different balance of price, comfort and practicality.
Below you will find our favourite cheap Cabin Max underseat bags for 2026. Every one hits that compact, airline friendly size and keeps the price as low as possible for the brand.
Some, like the Paxos and Manhattan, are among the very cheapest Cabin Max backpacks you can buy. Others, such as the Iseo roll top, cost a little more but add flexibility and everyday usability that may be worth the small extra spend if you travel or commute regularly.
A no nonsense underseat backpack that hits the 20 litre sweet spot and keeps the price extremely low, ideal if you just want a cheap Cabin Max bag that does the basics well.
The Paxos backpack is one of the cheapest ways into the Cabin Max range while still getting a purpose designed underseat carry on. At around 20 litres and shaped for the common 40 x 20 x 25 cm limit, it maximises what you can take on board without triggering extra baggage fees. The simple backpack format makes it intuitive to use and easy to carry through airports and on public transport. For the money, it is a very practical solution for quick trips, festivals and light outdoor overnighters where you do not want to fuss over luggage.
At this low price you should not expect plush padding, premium fabrics or lots of organisation. The Paxos backpack is quite basic, so heavy loads may not feel as comfortable as in more expensive travel packs. There is also less protection for laptops or tablets, so you will want a separate sleeve if you regularly carry tech. If you travel often and care about comfort or clever pockets, one of Cabin Max’s slightly pricier designs might be a better fit.
The Paxos under seat backpack is ideal for travellers who simply want the cheapest Cabin Max backpack that still does the job. It suits weekend city breaks, budget flights and light outdoor trips where you travel with a minimalist packing list. If you are new to cabin only travel and want to try it without spending much, this is a very low risk place to start.
The Manhattan keeps the budget friendly price tag but adds a more urban look, making it a strong choice if you want one Cabin Max bag for both travel and everyday use.
The Manhattan keeps the same budget conscious price point as the Paxos but dresses it in a more stylish, city friendly design. It still hits that 20 litre underseat capacity, so you are not sacrificing function for looks. As a backpack, it is easy to wear from airport to accommodation and doubles up nicely as a daypack once you arrive. For travellers who want one bag that feels at home in town, at work and on a plane, it offers very strong value within the Cabin Max line up.
The Manhattan’s focus on looks and keeping costs down means it is still a fairly simple bag underneath. Do not expect the sort of back support or ventilation you would get from a dedicated hiking pack. Organisation is likely to be limited, so you may need packing cubes to keep things tidy. If pure capacity and comfort matter more than style, the Metz or a more technical backpack might suit you better.
Choose the Manhattan if you want a cheap Cabin Max bag that looks at home on city streets and in casual work settings as well as on planes. It is a good match for students, commuters who occasionally fly, and anyone who wants one do everything pack for short trips and daily use. If you care a bit more about style but still have a tight budget, this is the sweet spot.
Designed to match Ryanair’s underseat allowance, the Metz gives you every last usable centimetre of space while staying firmly in budget territory.
The Metz is tailored specifically to Ryanair’s underseat size requirements, which makes it a superb cheap option if you fly with strict low cost airlines. At 20 litres with the 40 x 20 x 25 cm footprint, it lets you pack confidently right up to the limit without worrying about gate checks. The backpack design keeps your hands free and is more comfortable than a tote or shoulder bag when you are hustling through terminals. For the price, the peace of mind of a bag built exactly to those dimensions is a big selling point.
Because the Metz is cut so precisely to certain airline limits, it is not as forgiving if you overpack or want to use it beyond those flights. The design is functional rather than luxurious, so padding, harness and materials are all kept on the basic side to hold the price down. If you fly with a mix of airlines or want more everyday versatility, a slightly more general purpose design like the Iseo may make more sense.
The Metz is the obvious choice if you frequently fly with Ryanair or other airlines with strict underseat only tickets. It is perfect for ultra budget travellers who want to avoid paying for cabin bags, yet still pack confidently to the limit for a few days away. If your priority is compliance with those exact dimensions over everything else, this is the one to go for.
A 20 litre holdall version of the Paxos, with a shapesafe design that helps it slip neatly under the seat while still offering enough room for a long weekend.
The Paxos holdall keeps the same budget friendly 20 litre capacity but switches to a duffel style that many travellers find easier to slide under the seat. The shapesafe design helps it keep a low profile under airline seats while still giving you practical packing space for clothes and essentials. It is a good pick if you prefer grabbing a simple holdall handle rather than wearing a backpack, especially for short flights and weekend visits. At this price point, it is an easy way to add a dedicated underseat bag to your travel kit without overspending.
As a holdall, the Paxos shapesafe design lacks the hands free convenience of a backpack, which can be tiring if you are walking any distance. Internal organisation is usually minimal in this style of bag, so it can turn into a bit of a jumble unless you pack carefully. The focus on fitting under the seat also limits how much structure and padding it can have. Travellers who regularly carry laptops or photo gear will probably find it too basic.
The Paxos holdall suits travellers who prefer a simple grab and go duffel rather than a backpack, especially for short hops where you are not walking far. It works well for visiting friends or family, quick business trips and as a secondary underseat bag alongside a larger cabin case. If you want an inexpensive, compact holdall that behaves nicely under airline seats, this fits the bill.
The Iseo costs a bit more than Cabin Max’s absolute cheapest bags, but the roll top design and backpack format make it far more versatile for commuters and frequent flyers.
The Iseo Rolltop Backpack sits slightly above the rock bottom prices of the other Cabin Max bags here, but it justifies that with a more flexible design. The roll top closure lets you squeeze in an extra layer or compress the bag down when it is lightly packed, which is handy for everyday commuting as well as travel. It still works to the 40 x 20 x 25 cm underseat sizing, so you are not losing the cabin friendly advantage. For a modest bump in cost, you get a bag that feels more refined and adaptable than the very cheapest options in the Cabin Max stable.
You do pay a small premium for the Iseo compared with Cabin Max’s absolute cheapest underseat bags, so it is not the right choice if you are counting every pound. The roll top closure, while flexible, can be a little slower to access than a standard zip when you are rushing through security. As with the rest of this budget focused range, the harness and back system are still relatively simple compared with full featured outdoor packs.
Pick the Iseo Rolltop if you travel or commute regularly and are willing to spend a little more for extra flexibility. It is ideal for people who want a single underseat sized backpack that can handle work, university, day hikes and weekend flights. If your budget can stretch beyond the absolute minimum, this is the Cabin Max option that will feel most useful and adaptable day to day.
