SZLX Vacuum Compression Backpack Travel Bag with Pump — cabin fit for Ryanair and other airlines

What this is and why people buy it

This SZLX travel backpack is designed for cabin travel where you want your kit to fit within airline rules, but you also don’t want to waste space once you’ve packed. The headline feature is vacuum compression: the bag includes a sealed vacuum compartment and an outlet valve so you can expel air and make more room for bulky items. In practice, that can be handy for things like jackets, thicker layers, or travel bedding-style packing where compression makes the difference between “everything fits” and “something has to go”.

You also get a built-in pump (so you’re not relying on buying a separate one). On paper, it’s aimed at frequent flyers who pack efficiently, as well as students and professionals who take short trips often and want one bag that handles organisation without turning packing into a chore.

That said, it’s not perfect for every traveller: vacuum bags can be fiddly, and the vacuum-sealed section is described as having a very tight airtight zip that takes extra force to open. If you prefer grab-and-go packing with minimal fiddling, the process may feel like more effort than it’s worth.

Key points to know before you decide

The vacuum compression system is built into the backpack and uses a vacuum bag compartment with an airtight zip. You can use the electric pump for faster compression, or press manually to release air (depending on how you want to pack and whether you’ve charged the pump). The pump can also work for inflation/deflation, which broadens what you can do with the included pump nozzles.

There’s also a wet/dry approach to organisation, plus multiple compartments. The design includes a dedicated laptop compartment, a separate shoe compartment, and a back zip pocket for valuables such as a passport. The bag opens fully 180° like a suitcase, which is a real advantage when you’re trying to pack quickly in the airport or at your accommodation.

For cabin travel, the entry claims it meets Ryanair cabin baggage requirements and can fit either in the overhead compartment or under the seat. The product is also described as suitable for most airlines such as easyJet and Wizz Air, which is useful if you often mix carriers.

What stands out in everyday use

The vacuum feature is the most distinctive part of this bag. When you compress properly, you’re effectively shrinking the “bulky items problem”. It’s the kind of thing you notice most when travelling with layers, sports gear, or non-trivial packing cubes.

Another practical win is accessibility. A backpack that opens like a suitcase reduces the usual rummaging at the top of a bag. Instead of digging around, you can lay it out and reach what you need. That matters if you’re adjusting your kit during boarding, or if you’re repacking quickly before the next day.

The back luggage strap is also there to make it easier to attach the backpack to a rolling suitcase. And the honeycomb back cushion is described as waterproof and breathable, with foam shoulder straps designed to take pressure off your back—so it’s not trying to be just “compact”, it’s meant for comfort across a whole journey.

Pros and where it may fall short

Why it can be worth considering - Built-in vacuum compression with the option to compress quickly using the pump - A cabin-friendly format with suitcase-style 180° opening for easier packing - Dedicated laptop compartment plus a separate shoe compartment for organisation - Wet/dry design approach and a sealed vacuum bag compartment for odour isolation - Designed with travel basics in mind: suitcase strap and an internal back pocket for valuables

Limitations to keep in mind - Vacuum zips can be tight: the airtight zip is said to require extra force to open, which might slow you down when repacking - The vacuum approach adds a “system” to packing: if you’re the type who prefers throwing items into a bag with minimal steps, the vacuum process may feel like overkill - Cabin fit depends on airline rules and how you pack, even if the dimensions are marketed for Ryanair and “most airlines”, the real-world fit can still vary depending on what you’re carrying and how tightly you pack

Buying verdict

Is it worth it?

It makes sense if you want one cabin-sized backpack that combines airline-appropriate sizing with strong organisation, and you’re the sort of traveller who genuinely benefits from vacuum compression to fit more into less space. If you carry a 14 inch laptop and you like having separate zones for shoes, valuables and wet/dry items, this design is clearly built for convenience.

You may want to skip it if you dislike fiddly packing steps. The vacuum-sealed compartment is described as having an airtight zip that’s quite tight, and vacuum compression systems generally introduce more “setup” than non-vacuum alternatives. If your main goal is the simplest possible underseat/backpack routine, this may not feel as effortless as other cabin backpacks.
