ECOHUB Easyjet Cabin Bag underseat backpack 45x36x20cm, 30L, 13 pockets, waterproof recycled PET – Grey
Product description
What it is and the problem it aims to solve
The ECOHUB Easyjet Cabin Bag is an underseat cabin backpack designed for travellers who want to carry a properly sized bag on board without getting caught out by strict hand luggage rules. On paper, it’s the type of case you’d choose when you’d rather pay for a seat and keep your essentials close than risk a last-minute bag check.
This one is built around a specific footprint (45x36x20cm) and a stated 30L capacity, so it’s focused on the “under the seat” use case. It also opens like a suitcase, which can make packing feel less fiddly than bags that only zip fully from the top. If you tend to travel with a laptop/tablet, chargers, toiletries and a change of clothes, the pocket layout is clearly meant to keep things from turning into one big scramble.
The essentials in everyday use

The opening design is a big deal for day-to-day practicality. Being able to open the bag out like a suitcase helps you load shoes, clothes and bulky items into the main area without everything getting jammed at the top. There are also elastic straps in the main compartment to help hold items more in place.
For packing flexibility, there are side compression straps. That matters if you pack “light-ish” but still want the bag to sit comfortably, or if you’re returning with a few extra bits. A side handle is included too, so you can carry it as a holdall when moving between transport connections.
One practical touch: there’s a luggage strap loop so you can attach it to your suitcase and move through the airport with less wrestling. If your travel style is walking, rolling, then walking again, that kind of small convenience can save time.
Organisation and access: where the pockets earn their keep



This is an organised bag rather than a simple duffel. The front has large organisational pockets that are positioned for everyday travel items such as an iPad and notebooks, plus pens and paperwork. There’s also a top access pocket intended for grabbing travel documents and glasses quickly.
The hidden back pocket is a more secure-feeling spot for smaller valuables like a phone or wallet. And there’s a quick-access front panel zipper pocket that’s described as suitable for a toiletries bag—useful when you need faster access during security checks.
There’s also a key chain, which sounds minor until you’ve actually had to dig through a cabin bag to find keys at speed.
Waterproof, charging, and the eco angle

The recycled fabric is described as water-resistant, with a note that the material is made from 34 plastic PET bottles. It’s also said to be certified by GRS. In plain terms, it’s aiming to cover the two common travel complaints: “Will it cope with British weather?” and “Is there a more responsible angle?”
There’s also a USB charging port on the backpack. The intent is clear—keep your phone powered while you’re on the move—but whether it meets your needs depends on what power setup you use inside your bag. If you travel with a power bank, this feature could genuinely help. If you don’t, it may feel a bit like extra complexity with no payoff.

Who it suits best, and who should be cautious
It’s a solid fit if you want a compact, underseat-friendly cabin bag with lots of internal organisation, plus features for travel days like a luggage strap, quick document access and a phone charging port. The suitcase-style opening is especially handy if you’re packing in a structured way and don’t want to play “tetris” at the start of every trip.
It may not suit you as well if your trips require bigger, deeper packing volumes than an underseat-focused bag can comfortably hold, or if you prefer ultra-minimal bags with fewer compartments. Also, while it’s positioned for airlines where hand luggage rules can be strict, airlines and routes can vary—so it’s worth checking your specific airline’s latest underseat/hand luggage allowance before relying on any one measurement.
Should you buy it?

If you’re planning short trips and want an underseat backpack that’s built for organisation—documents up top, valuables in a hidden back pocket, toiletries on quick access, and bulk items held with straps—this is the kind of bag that can make your packing feel calmer.
However, don’t buy it on autopilot if you’re unsure about your airline’s exact limits for your ticket type and route. Double-check the sizing rules for your flight, and also think about whether you’ll actually use the USB charging port (it’s most useful if you carry a power bank).
Mini FAQ
Is the bag really designed to fit under the seat?



It’s designed around an underseat footprint (45x36x20cm) and an underseat cabin-friendly approach, with a stated 30L capacity. Still, it’s wise to check your specific airline’s latest cabin rules.
How easy is it to pack and unpack?
It opens like a suitcase, which should make packing and access simpler than top-only zips. The main compartment uses pockets and elastic straps to keep items more contained.
Does the waterproofing mean it’s fully waterproof?
It’s described as water-resistant rather than fully waterproof. That usually helps with light wet weather, but it’s not the same as guaranteed waterproof performance in heavy rain.
What’s the USB charging port for?
The bag includes a USB charging port so you can connect your phone during travel. Whether it works well for you depends on your power bank setup.
How much does it weigh?
The stated weight is 0.74kg, which is relatively light for a 30L underseat cabin bag.
