Metz for Ryanair Cabin Bags 40x20x25 Underseat Cabin Bag – 20L, RPET, Practical & Durable

What it is and what it solves

This is a compact underseat cabin bag designed to maximise your Ryanair allowance of 40x20x25, with a practical 20L capacity. It’s a soft-sided backpack that uses compression straps to squeeze in more without compromising comfort. If you prioritise keeping carry-on simple and organised, this bag aims to deliver on both space and accessibility.

How it’s built and what that means in use

The bag is crafted from 600D RPET recycled polyester, a material choice that leans into sustainability without skimping on durability. The recycled origin comes from plastic bottles, which is a plus for travellers who want a lighter environmental footprint. It’s designed to be tough enough for regular air travel, with padding across the shoulder straps, back panel and top handle to help when you’re lugging a fully packed pack through airports.

What stands out in daily use

On the practical side, you get a front pocket with dedicated holders for travel accessories and documents, a side pocket for a water bottle, and a rear trolley strap to attach to a suitcase when you’re navigating busy concourses. The layout is meant to support quick access and efficient packing, which can save time at security and boarding.

Strengths you can rely on

For travellers who fly with carriers that allow compact cabin bags, this Metz bag offers a straightforward, utilitarian solution. The use of RPET aligns with a growing preference for more sustainable luggage choices, while the underseat dimensions and 20L capacity provide a balance between space and portability. UK design and testing support the claim that it’s been evaluated against airline sizing in real-world conditions.

Limitations and things to watch

If you routinely pack heavy or require rigid protection for fragile items, a soft-sided bag with compression straps may not feel as protective as a hard-case alternative. The 20L capacity is practical for short trips or minimal packing, but it isn’t a large holdall. Also, while the bag is designed to fit under seats across multiple airlines, fit can still depend on the exact cabin configuration and overhead usage on the day of travel.

Who it’s for

This bag suits light to medium travellers who value compact cabin luggage that’s easy to carry, organised, and responsibly sourced. It’s particularly appealing if you’re flying with Ryanair, EasyJet, Wizz Air or similar carriers that emphasise underseat luggage rules and you prefer a backpack over a roller bag.

Who might want to think twice

If your trips require more space for week-long stays or you frequently carry bulky items, this 20L bag may feel limiting. If you rely on a rigid shell to protect delicate equipment, the soft-sided construction won’t offer the same level of impact resistance.

Before you buy – what to check

• Confirm the airline’s current underseat bag policy and how the bag’s exact dimensions sit within those rules.
• Consider your packing style: does a compact, compressible pack align with your typical travellers’ kit?
• Assess the weight you’re comfortable carrying, since the back and shoulder padding helps, but you’ll still be carrying the load.

How it compares in practice

In practice, this Metz bag sits as an economical, sustainable option that focuses on efficient use of space, quick access and underseat compliance. If you want a more rugged or more capacious option, you may look at larger cabin backpacks or a compact roller bag. For many short trips and frequent flyer routines, the combination of 20L capacity and thoughtful pockets represents useful real-world value.

Final decision

Final verdict

Is it worth it? Worth considering if you prioritise underseat compliance, practical organisation and a sustainable material approach for short trips. It’s a sensible, no-frills choice for travellers who want a compact backpack that travels lightly and stays organised under seat conditions.
