ECOHUB expandable underseat cabin bag for Ryanair 40x30x20 cm with removable wet pocket (beige)
Product description
The essentials
If you fly with the tight, rules-heavy budget airlines, an underseat carry-on needs to be practical rather than flashy. This ECOHUB bag is built around a 40x30x20 cm footprint, with a zip that lets it expand to 40x36x20 cm for extra space when you need it. On paper, that makes it easier to pack for an overnight or a weekend without forcing your whole trip into a single, rigid size.
There’s also a removable wet pocket attached externally, aimed at keeping toiletries or wet items separate and easier to clean. It’s the kind of detail that can matter when you’re juggling skincare, a small towel, or anything you’d rather not mix with dry clothes.
Worth noting: to pass a Ryanair bag tester, the manufacturer advises not packing it full (under 90%). That’s a small limitation, but it’s the sort of constraint you’d expect with strict airlines.

What you’ll notice day to day
The main “buying reason” here is the expandable layout. For short trips, having that extra room can help you avoid overstuffing—especially if you’re someone who packs a spare outfit, a small wash bag, and one extra layer “just in case”. In use, it’s fairly straightforward: you can zip it to expand when you need the extra space, and keep it tighter for the baseline underseat dimensions.



The wet pocket is the other element that feels genuinely useful. Because it’s detachable and described as leak-proof, you’re not left hoping your bottles behave. Instead, you can keep toiletries in the wet pocket and separate them from the rest of your items. It’s also said to be easy to clean, which is often where bags like this either win or annoy.
Where it shines
- Airline-friendly sizing approach: the bag is designed around the Ryanair 40x30x20 cm style dimensions, with an expansion option.
- Wet item separation: a removable wet bag can make packing toiletries more organised.
- Multiple carry modes: trolley sleeve for when you’re walking through stations/airports, plus shoulder straps when you need hands-free movement.
- Materials angle: recycled water-resistant fabric (made from 18 PET bottles) and reinforced seams are mentioned as part of the build.
It may not be a great match if…

It might not suit you if you’re the type who packs right up to the brim. Since the guidance for Ryanair testing says not to pack it full (under 90%), you’ll want a bit of breathing room in the bag. If you habitually fill every pocket and compress everything as tightly as possible, the expansion and strict airline fit could become a hassle.
Also, if you want a fully rigid, hard-shell structure or a “premium-looking” travel case, this reads more like an underseat duffel-style carry-on than a structured suitcase alternative.
Who it suits (and an everyday example)
It makes sense if you usually travel for short trips—think an overnight hospital visit, a weekend away, or a last-minute work trip—and you want one bag that can handle both dry clothes and a separate toiletries setup. A concrete example: you could pack a change of clothes and a light jumper in the main compartment, then put shampoo, deodorant, and any wet/used items into the removable wet pocket. When you arrive, the wet pocket comes off so you can rinse/clean it more easily rather than dealing with everything in the main bag.



Care & maintenance considerations
The fabric is described as water-resistant, and the wet pocket is said to be leak-proof and easy to clean. That said, for day-to-day upkeep, it’s still sensible to wipe away spills promptly and not leave liquids sitting around. With any expandable, zip-based bag, zips and seams also tend to last longer when they’re not constantly forced while tightly packed.
Is it worth it?
This ECOHUB bag is a strong “rules-aware” underseat option if you like the idea of sticking to a baseline 40x30x20 cm size for strict carriers, while still having the option to expand to 40x36x20 cm for a bit more packing flexibility. The removable wet pocket is a practical detail that can save you from messy packing trade-offs.

You may want to skip it if you regularly pack to the limit, because Ryanair tester guidance suggests staying under 90% packed to avoid issues. And if you’re after a highly structured, suitcase-like experience, this may feel more like a flexible duffel than a hard-sided carry-on.
