With many airlines now charging extra for both cabin and checked luggage, even a short break can end up costing more than expected. On most budget flights, only a small personal item is included in the ticket price, leaving passengers to look for compact bags that squeeze the most out of strict size limits.
One under-seat cabin bag designed specifically to meet Ryanair's rules has been reduced in price, offering travellers a cheaper way to avoid additional baggage fees. The Klostain Cabin Bag, which fits the airline's 40x30x20cm under-seat allowance, has been cut from £29.99 to £22.99. Often referred to as a 'Ryanair cabin bag' because it meets the airline's exact size requirements, it is also suitable for other low-cost carriers such as EasyJet and Jet2, where under-seat restrictions are similar. Beyond saving you money on travel, its deceptively compact design can accommodate a surprising amount, from clothing and footwear to toiletries, electronics and even snacks.
Storage Features and Design
The backpack includes a range of storage features, including a main section for clothes with compression straps to maximise space, a padded laptop sleeve and two side pockets for water bottles or umbrellas. There's also a front pocket for essentials such as passports and documents, an anti-theft back pocket for valuables and even a dedicated wet pocket for damp travel toiletries. For comfort, the bag features padded shoulder straps and a top carry handle. It is made from high-density polyester and is water-resistant, with an airflow back panel designed to reduce heat and sweating during travel.
Alternatives for Different Needs
Those looking for alternatives can check the Antler Discovery 28L Backpack, priced at £140, which comes in five colours and offers slightly larger dimensions at 45x31x20cm. However, it exceeds Ryanair's strict under-seat limits. For longer trips, the Stubble & Co Hybrid Backpack 30L, priced at £175, offers additional space and is designed for use in overhead lockers, making it better suited to extended travel or staycations. It is available in four different colours. Those looking for cheaper options can check out the American Tourister Take2Cabin Underseat Travel Backpack for £39 at John Lewis. Designed for seamless travel, this cabin-friendly backpack features top and side handles, compression straps and a dedicated bottle holder.
The Klostain bag is also available in different sizes, making it ideal for short trips or weekend getaways. The bag has also received positive reviews from Amazon customers, with many praising its practicality and value.
Customer Reviews
One shopper said: 'Excellent bag. Good quality and value. Lots of pockets and compartments for all essentials. Zips seem sturdy and the size is just right. Time will tell if it stands up to being used. I'm very happy with it so far.' Another wrote: 'Amazing backpack for travelling. Spacious, comfortable padding over shoulders and has a ton of pockets for every need even has a insulated compartment for keeping items warm or cool. Great value for money. Fabric feels sturdy and looks sleek.'
However, not all reviews were entirely positive. One customer said: 'Love this bag with all the compartments, very spacious and perfect size to fit below an aircraft's seat. Would have been nice if it had a strap around my waist to spread the weight whenever packed very heavy.' Another added: 'This bag is small. Those of you who reckon you can get 3 days-worth of clothes in it plus toiletries must be one of the Borrowers. It's a shame as it looked like a nice bag, but wasn't large enough for what I wanted it for.'
