SZLX Vacuum Travel Backpack with Pump — Ryanair cabin size 40x30x20

What it is and why people buy it

This SZLX vacuum travel backpack is built for one specific job: packing more into the same cabin-size footprint. It combines a vacuum compression system (to squeeze air out of a sealed vacuum bag) with a practical, suitcase-style opening that’s designed for quick access on trips. If you regularly hit that annoying point where your bag won’t close or your packing list keeps growing, vacuum compression can be a genuine way to buy yourself extra breathing space.

It also includes a pump in the pack, with the option to use it for inflation or deflation and different nozzles, so you don’t need to source a separate hand pump. On paper, it’s aimed at people who travel by plane often and want cabin-ready organisation rather than a bulky hard-shell case.

The essentials: vacuum compression and cabin-ready design

The headline feature is vacuum compression. The bag uses an outlet valve to remove air from the vacuum compartment, which can help create more storage room. You can compress it either with the electric pump for faster results or manually by releasing air through the system (useful if you don’t want to rely on charging).

For flying, it’s positioned around Ryanair cabin requirements, with external dimensions of WLH 40cm30cm20cm, and it’s described as fitting in the overhead compartment or under the aircraft seat. It opens fully 180° like a suitcase, which tends to make packing and checking simpler than top-opening backpacks.

A wet/dry design is mentioned for practical separation, plus a dedicated laptop compartment and a separate shoe compartment. There’s also a vacuum-sealed compartment with an airtight zip that’s described as quite tight, which is worth factoring in if you like quick, grab-and-go access.

What you’ll notice day to day

On travel days, the “feels organised” part matters. The dedicated laptop space and separate shoe compartment should help you keep everyday items separated from things like trainers, and the wet/dry approach is handy if you’re carrying swimwear or toiletries. The back luggage strap is designed to attach securely to a rolling suitcase, which can make airport navigation less fiddly.

There’s also a zipped back pocket for valuables such as a passport, positioned for discreet access. Comfort-wise, the honeycomb back cushion is described as waterproof and breathable, and the shoulder straps are padded with foam to take pressure off your back. None of this replaces a proper hiking rucksack for rough terrain, but for planes, stations and city walking it sounds more than reasonable.

One limitation to keep in mind: the vacuum bag’s airtight zip is “quite tight” and may require extra force to open. That’s not a deal-breaker, but it does mean you’ll likely want to be a bit more deliberate when you’re reaching into the vacuum section.

Pros, and where it may not be the best match

Where it shines: - If you want cabin-size travel that stays organised, the dedicated sections (laptop, shoes, wet/dry) are the sort of touches that make daily life easier. - Vacuum compression is specifically useful when you’re trying to pack bulkier items into a smaller space. - The pump being included (plus charging via Type-C) lowers the hassle of adding another accessory.

Where you might reconsider: - If you’re the kind of traveller who prefers to access packing compartments instantly, the tight airtight zip in the vacuum area could feel annoying. - Vacuum compression can add an extra step to packing/unpacking. If you’re travelling very light and already keep everything slim, the system might be more effort than benefit. - The product is focused on travel organisation and plane cabin sizing, it’s unlikely to be the top pick if you need a high-durability, all-day hiking load-carrier for heavy off-road walking.

Buying verdict

It’s a solid pick if you fly often, care about cabin-size compliance (with the stated 40x30x20 footprint), and like the idea of vacuum compression to squeeze more in without changing the bag size. It suits business trips, university trips and weekend trips, especially when you want a more “case-like” opening and compartmental structure.

You may want to skip it if you rarely struggle with bag space, hate multi-step packing routines, or strongly prefer compartments that open effortlessly every time. Also, if you’re buying mainly for quick access to everything on arrival, the vacuum zip being quite tight is a small but real friction point.
