What to know before buying

Listing details to confirm

The listing's 40 × 30 × 20 size claim and measured dimensions of 20D x 40W x 20H centimetres are consistent, but airline allowance depends on current rules and the packed bag's actual dimensions. The claimed 50% storage increase is not independently verified, and the separate water-resistance entry says “Water Repellent” while feature text calls the front compartment waterproof. Confirm the selected listing's exact configuration and claims before buying.

Who is it for?

A good fit for

Travellers looking for a compact backpack with vacuum compression for clothing.
People who want a separate compartment for a laptop up to 16 inches.
Commuters or travellers who value a rear pocket described as anti-theft.

Less suited to

People needing space for laptops larger than 16 inches.
Buyers who need independently confirmed waterproofing or a measured storage-capacity increase.

Aggregate ratings lean positive, with most ratings in the five-star category, but the distribution also includes lower ratings. Without written feedback, it is not possible to identify what buyers liked or criticised. The ratings alone do not verify the vacuum system's claimed storage increase, the bag's airline fit or its water protection.

Frequently asked questions

What are the listed dimensions?

The listing gives 20D x 40W x 20H centimetres and identifies the size as Ryanair 40×30×20. Check current airline rules and the bag's packed dimensions before flying.

Does it come with a vacuum pump and bags?

The feature text claims that vacuum bags and a pump are included, and says they can increase storage by 50%. Treat the capacity increase as a listing claim rather than a verified result.

What laptop size does it accommodate?

The listed maximum compatible device size is 16 Inches.

Is the backpack waterproof?

The specifications list its water resistance as “Water Repellent”. Feature text describes a waterproof front compartment, so the listing does not establish that the whole backpack is waterproof.
