ETRONIK for Ryanair cabin bag 40x30x20 underseat 24L (15 inch laptop) – black
Product description
Key takeaways
If you’re flying Ryanair (and want to avoid the usual worry about cabin-bag dimensions and fees), this ETRONIK underseat cabin bag is designed around the 40x30x20cm format. On paper, that matters a lot: it’s the sort of bag you can buy once and then travel with the same “fits the rules” set-up, rather than gambling with larger backpacks.
It also aims to be practical beyond Ryanair, with the same 40x30x20cm carry-on format positioned for Wizz Air and EasyJet too. The standout twist here is the 180° opening main compartment, which makes it easier to access and organise your things quickly—especially when you’re doing the usual pre-security rummaging.
That said, not every traveller will love it. A compliant-size bag is inherently more compact than a general-purpose backpack, so if you tend to pack bulky items or want maximum volume for longer trips, this may feel a bit tighter than you’d like.
What matters most (and what you’ll notice day to day)
The 40x30x20cm underseat approach is the whole point: it’s built to sit within the kind of cabin limits that airlines often enforce. The benefit isn’t just the label—it’s the day-to-day stress reduction. When your bag is the “right size category”, you spend less time thinking, “Will they measure me?”
In use, the 180° opening design is the feature you’ll probably notice most. With the main compartment that fully unfolds, you can lay things out more clearly instead of digging from the bottom. It can be genuinely helpful for spotting what you need quickly (and for keeping packing organised while you move through airports).
Also included is organised storage: a spacious main compartment, mesh dividers for categorising smaller items, and a dedicated laptop space.

Where it shines
This is a travel bag that’s trying to cover several roles without overcomplicating things:
- Airport practicality: the 180° opening makes it easier to inspect and organise when you’re constantly moving items around.
- Laptop protection approach: the dedicated 15.6-inch laptop compartment is designed to keep your device separated from other contents, aiming to reduce scratches from contact.
- Wet/dry separation: a wet bag for keeping wet items separate is a thoughtful add-on for things like a damp swim kit or a bottle that’s gone slightly wrong.
- Everyday versatility: beyond flying, the description positions it for school, shopping and general day-to-day use, so it shouldn’t feel “only for flights”.
What you should double-check before buying
Ryanair compliance is described as “fully compliant with Ryanair’s new hand luggage regulations”, and the same 40x30x20cm format is also said to meet free carry-on requirements for Wizz Air and EasyJet. That’s helpful, but it’s still worth checking the airline rules for your exact route/date and comparing them to the bag’s stated dimensions.
Also, while the bag includes a laptop compartment rated for 15.6-inch, that only helps if your laptop fits comfortably in the compartment shape and padding you expect. If you carry a thicker laptop, a tablet + keyboard, or accessories that add bulk, you may want to consider how you pack around the laptop zone.
Buying verdict
It’s not for you if you’re looking for a large all-in-one backpack for long trips or want lots of extra spare capacity. A 24L, cabin-sized underseat bag is designed to be compact, and that’s a trade-off.
It does make sense if you mostly travel with a “one bag, cabin only” approach and you care about sticking to airline-size limits—particularly Ryanair. Worth considering if you’d like an underseat bag that makes security-day handling easier thanks to the 180° opening, plus you want organised storage and a dedicated laptop compartment.
