SZLX Vacuum Backpack Travel Bag with Pump (cabin-size underseat with vacuum compression)

What it is and why people buy it

The SZLX vacuum backpack travel bag is a travel rucksack designed around one clear idea: save space by compressing your packed items using a vacuum system. Instead of just stuffing a standard cabin bag, this one adds a sealed vacuum compartment you can reduce to free up room—handy when you’re trying to fit everything into a strict underseat or cabin-size allowance.

On paper, it’s aimed at people who fly often and hate the “I packed too much” moment. It also opens up fully 180° like a suitcase, so you’re not digging around like you would with a typical narrow backpack layout. That mix—vacuum compression plus easy access—is the main reason it stands out.

Where it shines in everyday travel

A good test of a cabin bag is how quickly you can organise and reach what you need. This bag is built with separate wet/dry separation, multiple compartments, a dedicated shoe area, and a separate laptop compartment. There’s also a USB port, plus a back zip pocket that’s described as secure for passport and valuables.

A practical micro-scenario: imagine you arrive at the gate, you need your laptop for security, and you also want to keep shoes separate. You can place trainers in the shoe compartment, put your laptop in the laptop section, and keep smaller essentials organised in the other compartments. When you’re done, the 180° opening makes it easier to access the top items without emptying the whole bag.

The vacuum compression system (and its real limitations)

The bag includes a vacuum pump package, so you shouldn’t need to buy anything separately. The pump is described as usable to inflate and deflate, with multiple nozzles and a Type-C USB charging port. The vacuum compartment is also described as well sealed to help isolate items and reduce odours moving between spaces.

However, it’s worth noting that the vacuum compartment has a “hermetic zip” and may require more force to open. That’s not unusual for truly sealed systems, but it’s a genuine day-to-day consideration if you expect frequent access.

Cabin-size travel and overhead/underseat use

The bag is presented as cabin-friendly with Ryanair maximum requirements, and it’s also described as suitable for other airlines such as easyJet and Wizz Air. The external dimensions provided are 45cm x 30cm x 16cm, with a weight of 1kg. The design is intended to fit in the overhead compartment or under the seat.

Still, airline rules can vary by route and aircraft, so it’s sensible to double-check that your specific trip’s size limits match these dimensions and how strict your airline is about wheels, handles, and packing shape.

Comfort and carry options

This isn’t a fashion backpack, it’s built for travel carry. There’s a rear strap intended to secure it onto a rolling suitcase, and the back is described as padded with an alveolated, waterproof and breathable design. The shoulder straps are foam and meant to keep the back feeling cooler during longer journeys.

If you’re mostly using it for short flights and station-to-airport days, the carry style makes sense. If you’re planning long hikes or heavy loads off-airport, you may find a more performance-focused hiking pack more comfortable—this one is tuned for flight cabin use.

Is it for you? A quick buying decision

It’s a good fit if you want a cabin-sized underseat backpack/hand luggage rucksack with vacuum compression, plus separate organisation for shoes and a laptop, and you’re happy to use a pump system to save space.

It may not suit you if you prefer ultra-simple access (because the vacuum compartment’s hermetic zip can take more effort), or if you only pack lightly and won’t benefit much from compressing items in the first place.

It makes sense if you travel for work, university, or weekend trips and you regularly hit the limits on hand luggage space. You’ll likely get more value from it when you pack bulky essentials and want a repeatable way to compress and tidy.

FAQ

How does the vacuum pump work here?

The bag includes an electric vacuum pump. The description says you can compress by using the pump through a valve/exit system, and it can also be used to inflate/deflate, with different nozzles and a Type-C USB charger.

Will it definitely fit Ryanair and other airlines?

It’s described as meeting Ryanair cabin requirements and being suitable for easyJet and Wizz Air. The dimensions and weight are provided, so the safest approach is to compare them with your airline’s current rules for cabin/underseat sizing.

Can I access the vacuum compartment quickly?

Possibly, but the vacuum compartment uses a hermetic zip and is described as requiring more strength to open. If you expect to open it often, keep that in mind.

Does it fit a 14-inch laptop?

The product name states it’s for a 14-inch laptop. The description also mentions a separate laptop compartment, which is the more practical detail for day-to-day storage.

Final verdict

Should you buy it?

Buy it if you want a cabin-size travel backpack with built-in vacuum compression, a pump included, and organised compartments for shoes, a laptop, and wet/dry separation. Skip it if vacuum compression doesn’t matter to your packing style, or if you’re the type of traveller who wants effortless, quick access to every compartment every time.
