What to know before buying

Listing details to confirm

The listing describes the bag as 40 × 30 × 20 cm and as meeting Ryanair's maximum hand-luggage requirements, but airline rules and fit can depend on the packed bag and current policy. Confirm dimensions and allowance for your journey. The external dimensions are listed as 20D x 40W x 20H centimetres, while another feature describes them as width × length × height at 40cm*30cm*20cm, so the orientation of the 30 cm side is unclear. The listing calls the bag waterproof and also describes a waterproof, breathable back cushion, but does not provide a test rating or clarify protection for the whole bag. It says the pump uses a Type-C charging port and also refers to a USB charger, without specifying the charger supplied. The airtight zip is described as tight and requiring extra force to open.

Who is it for?

A good fit for

Travellers wanting a compact-format backpack with a vacuum-compression compartment and pump.

Less suited to

Anyone who needs verified water-protection performance or a clearly specified pump charger in advance.
Travellers who need confirmed dimensions in a particular orientation or a guaranteed fit under an airline seat.

Aggregate ratings are mostly in the five-star category, with a smaller spread across lower star ratings. Without customer-comment evidence, these figures do not show what buyers liked or what prompted lower ratings. For travel buyers, fit, the tight airtight zip and the stated laptop limit are practical points to assess against their needs.

Frequently asked questions

Does the backpack include a vacuum pump?

The product description says a pump is included and does not need to be purchased separately. The package contents are not independently itemised in the supplied listing details.

What are the listed dimensions?

The stated external dimensions are 20D x 40W x 20H centimetres. A separate feature describes 40 cm × 30 cm × 20 cm, so check the selected listing for clarification before relying on a specific orientation.

What size laptop does it fit?

The listed maximum compatible device size is 14 inches. The supplied information does not give the compartment's internal measurements.

How does the vacuum compression work?

The listing says air can be expelled through an outlet valve, either manually or with the pump. Compression is intended to reduce wasted space, but no measured capacity gain is provided.
