Who Are CabinZero?
CabinZero is a UK-based travel gear company founded on a simple idea: travel should be easy, and your luggage should never hold you back. With a clear focus on cabin bags that fits airline restrictions and a design ethos that prioritises durability, functionality, and style, CabinZero has developed a loyal following around the world.
What sets CabinZero apart is their obsession with one-bag travel. Their cabin bags are designed to replace bulky suitcases and help you move freely from plane to train, city to mountain. Their designs are minimalist but versatile, making them equally suitable for weekend breaks, long-haul adventures, and outdoor getaways.
The CabinZero Classic Backpack Range
The Classic Backpack range is CabinZero’s flagship collection. These cabin bags are available in three sizes: 28L, 36L, and 44L. Each one is built with a durable water-resistant polyester fabric, lockable zippers, compression straps, padded shoulder straps, and a luggage tracking system powered by Okoban. They're incredibly light, stylish, and built to last.
Let’s break down each size and what makes it ideal for different types of international and frequent travel.
The Perfect Under-Seat Cabin Bag: CabinZero Classic Cabin Backpack 28L
Dimensions: 39 x 29 x 20 cm
Weight: approx. 600g
The 28L version of the Classic Backpack is specifically designed to meet the free under-seat bag size limits of budget airlines like Ryanair. Measuring 39 x 29 x 20 cm, this cabin bag fits snugly under the seat in front of you, meaning you avoid additional baggage fees and skip the queues for overhead lockers.
Don’t let its compact size fool you. This is a roomy and efficient bag for light packers. There’s space for clothes, toiletries, electronics, and even a book or two. With its padded shoulder straps and top/side handles, it's also incredibly comfortable and easy to carry.
If you’re a frequent short-haul flyer who wants to avoid check-in desks entirely, the Classic 28L is a no-brainer cabin luggage option.
The Versatile All-Rounder: CabinZero Classic Cabin Backpack 36L
Dimensions: 45 x 31 x 20 cm
Weight: approx. 760g
The 36L Classic strikes the perfect balance between compact size and generous capacity. It still qualifies as cabin luggage on most airlines (check specific policies), yet it gives you significantly more space than the 28L. If you're going on a long weekend or want to pack a few extras, this is your ideal cabin bag.
It’s a favourite among travellers who want one bag for both city and country. Think Dublin to Budapest with a detour to the Carpathians. The extra volume is especially handy if you’re bringing gear for hiking or colder destinations.
Its streamlined profile makes it easy to manoeuvre through airports, public transport, and cobblestone streets alike. And as with all CabinZero models, the Classic 36L includes lockable zips and a tracking tag, so it’s secure and traceable, too.
Maximum Capacity: CabinZero Classic Cabin Backpack 44L
Dimensions: 55 x 40 x 20 cm
Weight: approx. 760g
For those who want to travel with nothing but cabin luggage - even on longer trips - the Classic 44L is your champion. Designed to the maximum dimensions allowed by most airlines for cabin luggage, this bag offers an impressive amount of space without tipping over into hold luggage territory.
You can pack clothes for a week or more, a laptop, a pair of shoes, and still have room left over. Despite its size, the 44L still fits into the overhead compartment of most planes and meets Aer Lingus’ carry-on limits.
It’s especially suited to remote workers, backpackers, and anyone pursuing a lifestyle of efficient, flexible travel. With its robust construction, it’ll handle everything from transatlantic flights to back-to-back train journeys.
