Underseat Foldable Travel Duffel Bag for Ryanair Cabin Bags (40x30x20) – 20L Mint Green with Shoulder Strap
Product description
The essentials
If you’re trying to avoid paying for extra luggage on short flights, an underseat bag is usually the practical move. This for Ryanair underseat foldable travel duffel bag is built around the idea of fitting in the cabin footprint (the listing specifically mentions new Ryanair Airlines dimensions of 40x30x20cm). It’s a 20L holdall style bag in a mint green colourway, with a shoulder strap included, so it can work both as an underseat carry and as a grab-and-go tote for everyday outings.
Is it going to magically fit every edge case? Not necessarily. Bag fit can depend a lot on how strict the airline and staff are, plus how full the bag is. Still, on paper this one is aimed squarely at the kind of dimensions people check when planning a Ryanair cabin bag and an overnight light packing routine.
Key features

The bag is made from a nylon-like fabric described as thicker and more durable, with a water-resistant finish intended to protect your items from light rain or wet conditions. That matters because underseat bags tend to get handled, bumped and occasionally exposed when you’re heading through wet weather at the station or airport.
It’s also designed to hold its shape when empty, which is a small thing until you pack and unpack repeatedly—then it helps the bag look less floppy and stays easier to slot under a seat.
For carrying, there’s a strap/pouch arrangement intended to allow the duffel to sit over the handle of a common suitcase. That’s the kind of detail you feel on a longer walk when your hands are already full.
What it’s like to use day to day



Imagine you’re travelling for two or three days: a compact jacket, a couple of outfits, toiletries, a small charger pouch and maybe a book. With this bag, you can fold it away for storage at home, then open it up when you’re packing. Once you’re at the airport, the goal is simple—drop it under the seat so you don’t have to think about it again during boarding.
The shoulder strap adds flexibility too. If you’re moving from plane to hotel or from car to venue, you can carry it without relying on a suitcase handle. And because it’s described as holding its shape when empty, it’s less awkward when you’re packing on the go.
Where it shines (and where it may fall short)
Where it makes the most sense is for light travel and quick trips: overnight stays, weekender-style packing, gym or sports use, yoga gear, or even a weekend shopping/camping day where you want one bag that can be carried in different ways.

The water-resistant fabric is a helpful baseline, but it’s worth tempering expectations. “Water-resistant” doesn’t mean fully waterproof. If you expect heavy rain or long exposure, you’d still want to pack key items in a separate protective pouch.
Who it suits
It’s a solid pick if you want a single underseat carry that’s designed with Ryanair cabin bag dimensions in mind, and you prefer the convenience of a duffel/holdall format over a rigid hard case.
It may not be the best choice if you tend to overpack and rely on the bag expanding—overfilling is exactly where “fits underseat” plans can get messy. Also, if you need lots of internal organisation (separate compartments, dedicated pockets), the listing doesn’t give those details here—so you may have to use packing cubes/pouches to keep things tidy.

Should you buy it?
This is worth considering if your main aim is to travel light with an underseat bag that matches the 40x30x20cm Ryanair cabin bag footprint mentioned in the listing, while also getting a shoulder strap and a suitcase-handle carry option. It fits the “grab it, pack simply, store it under your seat” style of trip planning.

Don’t buy it expecting guaranteed fit in every situation, especially if you know you overpack or want a very structured bag. Also, treat the water-resistant claim as protection from light wet conditions rather than a substitute for proper waterproofing.
