Underseat cabin bag 40x30x20 for Ryanair
Product description
Key points
If you fly with carry on rules that can be tight, a correctly sized underseat bag makes life easier. This VMIKIV cabin bag is built around the 40x30x20 cm limit, with a main compartment around 40x30x18 cm according to the manufacturer description. It is a compact travel backpack that you can use day to day, then keep for short trips and weekend travel when you want to stay light and organised.

One standout detail is the hidden anti theft pocket on the back, which helps you keep valuables more secure than a front pocket. You also get a separate wet pocket for wet towels, toiletries, or dirty clothes, plus several smaller inside pockets to sort essentials. And there is a side cable hole so you can thread your charging cable through and keep your hands free while your phone charges on the move. ✈️

Benefits



This backpack focuses on practical travel convenience, especially for airlines that charge for items that exceed the stated limits. The manufacturer states the underseat bag sizing is designed to meet Ryanair’s maximum under seat bag 40x30x20 cm, and it is also described as suitable for Vueling. You should still note that if the bag is over the stated size, additional fees may apply, and the brand also points out that measurements can vary by manual measuring methods, so a 1 to 3 cm error can happen when the backpack is full.
Comfort matters too on days when you are walking through airports or stations. The straps and back are described as using breathable honeycomb material, and the shoulder straps are padded to help with carry comfort. There is also a luggage strap to attach to a suitcase handle, so you can share the load more easily when you are rolling luggage. 🤝

When it comes to day to day use, the included side cable hole can be handy if you like charging on the go, and it also helps with listening to audio hands free. For keeping items arranged, the wet pocket is separate from the rest of the bag, which can help you separate damp or dirty items from cleaner essentials. It also includes a laptop compartment, which supports use cases like commuting or a short trip when you want one bag for everything. 👜


Important notes from the manufacturer help you shop with confidence. The package includes the backpack only, and cables and a power bank are not included. For Wizz Air, the brand asks you to measure the backpack when it is full, since that is when the true fit against airline requirements is most relevant. ✅

Who it suits best
It’s a good fit if you want one compact underseat carry on bag that matches a 40x30x20 cm style limit and keeps essentials organised for 1 to 3 day trips. You’ll like it if you prefer an everyday daypack feel, with padded straps, a breathable back, and a luggage strap for easier movement through busy travel days. It may also suit commuters who want a small laptop compartment and a layout that makes sorting easier.

It might not be a great match if your routine depends on carrying larger items that regularly push beyond the stated size limit. You may also want to skip it if you require accessories like charging cables or a power bank, as those are not included in the package according to the manufacturer description. Overall, it suits travellers who care about staying within cabin bag rules while having anti theft storage and clearer pocket organisation for the items you access most often.
